2.5% is nice, but sometimes you have to take a 1% gain to avoid taking a 1% loss, and if you set your exit just above 1% it covers the trading fees on binance.  And if I make 3 trades at 1% in a day, which is, most of the time pretty easy using the depth charts.  I like to look at the total BTC on the order book cumulatively of over 100BTC in Bids/Asks.  That way the faking out of the order book isn't as easy, and whales have to dump large or buy large in order to move it much.  Also if the Volume is over 1000BTC/24Hr is another one of my rules for trading a particular coin.  For example the only coins right now on binance for considering a trade in are : ADA, TRX, ZIL, FUN, XRP.
That's how we get around the misleading of the orderbook.
