But now I have discovered that binance offers the possibility to trade without commissions for a limited time. So if I set the stop loss at the same price as the entry price (or one cent below the buy price) it should be relatively easy to be profitable.
On the trades I lose I would only lose a few cents and on the trades I gain I would gain much more by using the trailing stop...this commission free trading sounds too nice to be true, doesn't it? is there a catch I don't know about?
If you set a stop loss at the same price wouldn't the order get executed in less than a minute.
We know how volatile the market is and 2% - 3% fluctuations are very normal in crypto.
Although trailing stop loss is a good feature you should reconsider your strategy and plan accordingly.
Try making a few practice trades and then consider investing bigger amounts.
