Binance trading program
I wrote a program to automatically trade cryptocurrency using the Binance library.
I am very tired of watching the trend while trading, and I have implemented the logic that I trade in as a program.
I do not want to encourage you to use it because you may lose money. Please refer to it and hope to have a hint.
I'll introduce the logic briefly.
- The base amount is the last sale price or the current price.
- If the present price is bigger than the base price, it is sold. If it is small, it is bought.
- Buying: If the price falls below a certain percentage and the specified percentage and price go up in the min price, the market will be bought.
- Sell: Sells in the market if it is higher than the specified percentage and the price is lowered by the specified percentage in the max price.
- When a transaction occurs, a message is sent to the telegram.
- Logs are logged at regular intervals.
- Save the price data as json each time, and refer to the data when reloading and reloading the program.
- Bring the market price at a set time interval and repeat steps 1-7.
Below is the source I wrote.
