Binance doesn't have any market surveillance tools in place. They could do whatever they want.
Has anyone here noticed how charts on Binance look different than other exchanges? Take this ETH/USDT chart for example:
On the 14th of March there was a spike down while on other exchanges it happened on 12 March.
When analysing the markets with Fibonacci and Elliott wave theory the charts look very unnatural on Binance, while on Bitfinex everything seems normal.
I wouldn't be surprised if they manipulate their own market at places where there are many stoploss orders. So they can get more trading fees. Often you see that the spikes down are bought immediately.
