At Napbots, we do not work with TP (Take Profit) and SL (Stop Limit). Our bots work with the sliding window system. When these windows indicate a change of signal, the bot receives a buy or sell order.
After many tests, this technique has proven to be more profitable than using TP / SL.
Indeed, crypto-currencies have a very high volatility, so it is sometimes impossible to reach a TP / SL. Another consequence would be not being able to get back on the train after exiting a trade.
