Greetings to all dear Steemit fellows and to our Respected Professor @yousafharoonkhan so here Respected professor taught us about Exchange order book and it's use and how to place different orders
I am much excited to learn about these orders yes it was little bit difficult at first for me to understand but however the way in which professor explained us is really amazing and in easy wordings, before moving to my homework I want to highlight this topic.

INTRODUCTION .

So as you all know very well that in this week professor has given us lecture on Exchange order book it's method that how to use it and it's benefits.
As it has been clearly explained by our professor. We have been introduced to what order books are, how order books are different from our local markets, how to find order books and how to place different orders on an exchange platform,each and every topic is highlighted here beautifully.

1.What Is Order Book And How It Crypto Order Book Differs From Our Local Market.

The order book In the Cryptocurrency market refers to a book that has a pair of crypto asset with their prices set by the trader, in another words an order book is a list of the recorded buy and sell orders placed by the traders in the market in which a trader sets the price accordingly his own will. As it entails all the buy and sell orders of crypto asset as I earlier mentioned.The order book helps traders to know the current pricing of the asset they want to trade in and it also allows traders to set the price at which they want their assets to buy or sold other assets of interest,one thing more is that the order placed if not set at market is listed in order book until the market matches the set value given by traders.
As professor as explained as very purely and clearly that this order book is almost similar to our daily order book and how beautifully and in easy wordings he taught as that this order books is very similar to our daily order book.
So first I'll put highlight of order book in CRYPTOMARKET
In cryptomarket the order book keeps a record of all the trades but in PAIRS
For example UNI/USDT pairs
Same like that these orders are as Sell orders as well as buy orders (In pairs only)

SELL ORDERS
So let's suppose you want to buy USDT,then you will sell UNI in return you will able to buy USDT,and this trade will be recorded under the section of sell orders.

BUY ORDERS
So same the way if you want to buy UNI then you have to sell USDT in return you will buy UNI and this trade will also be recorded in the section of buy orders.

This concept of order is just simple and easy hope so you will understand,let's practically I'll differentiate between these Cryptomarket order book and Local market order book.

The major difference is between these two orders book is that in Local market no pair trading is involved,traders uses a currency in transactions and in cryptomarket trades are in pairs for example UNI/ USDT pairs.
Crypto order book contains a record and list of all the open orders that have not been executed. While local market, there are no record of open buy and sell orders.

One of the Biggest difference between these two are as Crypto order book, anyone can buy and sell any cryptocurrency asset anywhere in the world. While a local market requires a physical location to buy and sell items

And the other difference is that,In crypto order book, both the buy and sell orders are transparent and visible for everyone. While local market, only the sell prices of items are visible.

Crypto order book operate more like a trade-by-barter system where the buyer and seller can buy or sell a specific cryptocurrency asset for another cryptocurrency asset. For example, a buyer has USDT and wants to exchange that with UNI at a desired price, the buyer would choose a pair that matches his/her needs to trade the cryptocurrency. Where as in local market, there is no exchange of items, rather the buyer would pay using money to get his particular item.

One of the big difference is also that In crypto order book, it is easy to evaluate the demand and supply of the particular cryptocurrency pair. While in local market, it is not easy to evaluate the demand and supply of the different items.

Technical analysis also occurs I means local market is not do efficient as their prices are fixed and are controlled by authority making people I mean under government authority where as in cryptomarket technical analysis plays keen role by using various indicators like MACD ,RSI etc.

Local market has a single trading option where as in cryptomarket various options in which includes limits order, stop limit orders, and many more.*

2.How To Find Order Book In Binance Exchange Through Screenshot And Explanation Of The Given Words.

So here we are going to answer our 2nd question asked by a Respected professor so I'll be using my binance account in this regard.
So firstly just open your browser or if you have downloaded your binance app whatever you want to use just open it.
Then logged in if you are logged in it already that will be too nice.
As I have installed BINANCE APP so I'll open it you will see the window like that as shown in below.

After that just click on market I'll show it's screenshot under below s...
here you wi see the different options like
Spots markets
Favorite
zones
Future market

After that
Here you will click on the spot market as shown in the screenshot below and you will then choose a pair of your choice for the demonstration.

I chose the ADA/BNB pair as I have already invested in ADA as well. You can search for your desired coin in the search bar on the right as shown in the screenshot.

After clicking on the ADA/BNB pair as shown in the screenshot. A new tab will open you will see it like that I'll show it's screenshot below.

The order book in RED is the SELL BOOK ORDER

The one in GREEN is the BUY BOOK ORDER.

TRADING PAIR

In the Cryptomarket a trading pair means the two coins or two assets which can be traded against each other.
For example the pair I chose above ADA/BNB. This is a trading pair. Which means you can sell ADA and buy BNB or you can sell BNB and buy ADA. All the trades are recorded in the exchange order book.

So further here I'll also show you Fiat piar.

FIAT PAIR:

fiat-based pair works the same as a cryptocurrency-based pair, except one of the assets being exchanged is a fiat currency which means dollars. For example BTC/USD

SUPPORT AND RESISTANCE

The term support refers to the lowest point of asset's value. After the support level the the downtrend usually stops and starts going up. If sometimes a coin's price brraks the support level then a huge crash is expected.
The support level is the cheapest point to invest in a coin. People usually buy at this point and then make profit when the trend goes upwards, and where as in Resistance the peak maximum point of an asset's price. At this point the price is the top most and people usually sell their coins at this point to make huge profits. So when people start selling in bulk, the prices start gradually going down.

LIMIT ORDER.

Limit order is type of transaction where the buyer or the seller wants to sell the asset at some price higher than the current price (market price).
For example. The current price of ADA is $3.5 but I want to sell it in $4.0 so I will set a limit order of $4.0
The order will be completed as soon as the price of the coin reaches $4.0

The same way it happens when buying a coin.
For example I want to buy ADA at $2.4 but it is currently at $2.6 so I will set a limit order of $2.4 so whenever the coin value regresses to $2.4 the transaction will automatically complete and buy me the coin at my desired value.
hope so you will got my point as I tried to explain it in easy wordings.

Now we moves to professor's next task about MARKET ORDER

Market order is that type of transaction where the trader sets a price which is accordingly to the market price. it means the original price of market, in this type of order takes no time in getting completed as the buyer is getting his desirable amount and the seller is also selling in what he wants.
For example: the current price of ADA is $2.50 if I place an order at this same price. My order will be carried out immediately.

3.Explain the important future of order book with the help of screenshot. In the meantime, a screenshot of your exchange account verified profile should appear.

So here I am going to answer of Professor's next question before proceeding I'll show you my verified Binance account as shown in below.

Features of the order book

The order book as explained keeps the record of all the trades occuring of a pair. It also keeps the information regarding the market capitalization, volume, supply/demand etc as I mentioned earlier.
do lets demonstrate the order book from my binance account.

As this screenshot represents the order book of the ADA/BNB pair.

The green section and arrow shows the buy orders and the red section and red arrow shows the sell orders.
The prices are very clear through this order book.as seen clearly.as shown above

The orders are continuos and will carry out with the course of times. Obviously there are thousands of traders trading so the values keep changing it means it not going in one direction ups and downs are seen clearly.

So in next step I'll practically show you with screenshot that how trading is done through these orders.

Buy order

This basically means to get a cryptocurrency in exchange of some other cryptocurrency or USDT
For this we have to select a trading pair. For example I wanted to buy USDT from VET.So I. order to show these orders I logged in to my binance account. Then clicked on market and then on SPOT MARKET from there I clicked on FIAT MARKETS then I will click on VET/USDT as shown in the screenshot below to be specifically clear.

After clicking on the pair a new tab will open with an order book present. There we will click on buy as shown in the screenshot below.
On the buying option fill the the details like how much VET you want to buy. An then it will show you the amount of USDT needed to process this transaction.
As you can see in the screenshot below that I chose to buy 30 VET which showed me a total of 2.825 USDT.

so once you have decided the amount you can hit the buy Vet button, and simply you are done.

SELL ORDER

As same like firstly I have shown in screenshot that how to place buy order then I put desirable amount and I got vest same in this option let's consider that you want to exchange your asset in return of a different asset. To demonstrate the example I will choose VET/USDT pair. As shown in the screenshot below.

Now simply click on Sell put desirable amount you want to sell for sell orders.
As shown in the screenshot below. I chose to sell 30 VET which will give me
2.880 USDT as shown in pic below.

4.How to place Buy and Sell orders in Stop-limit trade and OCO ,? explain through screenshots with verified exchange account.

So after sell orders and buy orders now I moved to explain about to place Buy and Sell orders in Stop-limit trade & OCO.
As before showing you practically let me explain you in details that what is a stop limit order and how it works.
Actually when you can't observe or watch your trade all day you feel little bore to observe every time then one method you would like to use is stop limit order,as many times I used these orders in steem buying and selling process of steem, for example if you want to buy 14 steems of 1 SBD but currently you are seeing that at price of 1 SBD you will only receive 12 steems so in order to get profit you use to set your desired amount of steem and use to set stop limit offer, in short and easy wordings let me explain you that stop loss is activated so in which you don't get loss , as the limit order is kept to get your desirable profit.
Moreover in stop price it is the start of your desired or targeted asset price where as in Limit order it is the lower Limit of the target price and mostly at this price the limit order gets completed as I earlier mentioned it is lower Limit order.

So next part of the same question How to place stop-limit order.

Same like that First of all you have to chose a trading pair for this option. and again I will choose the VET/USDT pair to demonstrate you the option of stop-limit order, and will try my best to explain it easy as possible as I'll do.
So same like that just go to market and the way I earlier mentioned I have just again clicked on VET/USDT there new window will open ,here I am sharing my binance account's screenshot where I am doing these orders practically.

As you have seen in screenshot, now just put your desirable stop order and you are done.

How to place Buy stop-limit order.

Here I am demonstrating a buy stop-limit order on VET/USDT, you can see here I have given below screenshot of my Buy Stop-limit order.

I set stop price at 0.12 (VET per USDT) and actual limit price at 0.09394(VET per USDT)
When the price of VET reaches the stop price, the transaction will become the limit order and the order will be executed at this price,it means when price will reaches at my desirable amount the order will be executed.

Sell stop-limit order.

Here once again I'll chose the VET/USDT pair and I set stop at 0.10950 and limit at 0.10939, so When the price of vet reaches the stop price, the order will be executed,as shown screenshot below you can clearly check this sell Stop-limit order.

How to place buy sell order in OCO.

Now here let me explain you about OCO trade as per explainations of Respected professor @yousafharoonkhan it is the short form for One cancels the other. trade.
In which traders can place two orders those are limit order and stop limit order Let me explain you that in this only one of the order either Limit order or stop-limit order would be executed,while the other would be cancelled automatically, as by its name One - cancels - the - other (OCO).
if I explain it in my own and easy wordings then it says that it is a type of order in which one gets completed and the other gets cancelled automatically.
Lets suppose with a example,if in a trade if we set the limit as well as the stop-limit order and the limit order gets done, the stop limit will be cancelled automatically. Similarly if the stop-limit order gets completed the limit order will cancel, how simply is this.

So here lets demonstrate how to use this option in our binance account it is so easy just I am going to start with giving you screenshots.
Same process as you have done already just go to your binance account and login to your binance account select the trading pair in the market. Select the buy/sell option and Now here chose the OCO.

Placing of Buy OCO order.

Same once again I will choose the VET/USDT pair for this trade too, here a limit order and a stop-limit order is placed. The OCO Limit the price is set at 0.14 and the stop-limit order at 0.12 as shown below in screenshot.

If the market hikes up to 0.14 as I have set my amount,it will trigger the limit order and the order will be executed. Which means the stop limit order got cancelled automatically. And if the price goes down and touches the stop price of the stop-limit order then the stop-limit order will turn in limit order and will be executed and in this way cancelling out the Limit order.

Placing Sell OCO order.

Now executing the sell OCO order. I put the OCO limit at 0.10950 and for the stop-limit order, the stop price at 0.10935 and the stop price at 0.10919 as shown in screenshot below.

so same the way it will do as If the price reaches the limit price of the limit order, it will be completed and the stop-limit order will be cancelled. If the prices go down and hit the stop price, the stop-limit order will be triggered and the order will be carried out at limit price of the stop-limit order. Cancelling out the limit order.

***I tried my level best to put highlights on these orders with screenshots and I have done it by explaining in my own words as well as giving screenshots of my practical method.

5.How order book help in trading to gain profit and protect from loss?share technical view point, that help to explore the answer.

So I am here to give my best explanations on the last question asked by our Respected professor,so let me explain you in my own wordings that there are so many ways of getting profit from a cryptomarket using the order book and as many of them are well explained by our Respected professor and following him as I tried to explain here by doing practically and as you seen that how easily you can get benefit by understanding these orders,as I earlier mentioned that let's suppose may be a trader can't watch his trading all day so he use to set stop limit orders (all these mentioned orders)

So in this Lecture we have learned many things about orders different types of orders and how order book is necessary tool in the cryptomarket,we have seen various futures of the order book those are the stop limit order,the OCO order and market Order etc,the major and highlighting feature of these order are as it helps you in minimizing the risk of losses and maximizing the profits.
As the order book helps to keep all tracks of the history of any transactions done by the traders on the platform,it also helps to know the current price of the currencies.it also shows the volume of each crypto pair and giving the traders more information on the volatility level of the asset and also it indicates the right direction of market I mean that Which crypto currency is going high or down to take quick decisions reducing the all risk factors.
Moreover the use of stop limit orders feature enables the traders to set his loss limits without extending bit further,it completely gives the trader full protection from being at risk and getting enough profit, without sitting all day.
TO be honest the stop limit feature is the best as I earlier mentioned that in past I have used it many times and believe me without sitting and observing it all day it gives the traders good profit without any risk I mean it is a risk free trading.
As using the features of the Order Book simultaneously with the technical Indicators such as RSI AND MACD will also help you alot in the analysis.

CONCLUSION

As I have mentioned many times earlier that it was very knowledgeable and informative Lecture we have learned many types of trades, the real excitement is that in this you can trade without getting any risk of loss, by these kind of trades you don't have the fear of jumping the market which can lead you at loss,no way but yes you can earn good profit from these types of Tradings
but you should have atleast some understanding about it that how to set stop limit order how to fill out all demands etc. To be honest basically these all are very easy to use and it gives you good profit but again I'll use to mention that you should have atleast good knowledge of it.

At the end of my Homework submission I'll specifically thanks to our Respected professor and will request him to review my Homework as to be honest it took my alot of time to complete it...

Once again Thank you for reviewing my Task.
