If I set a 3% loss on my initial investment as a stop loss and a 10% profit as a stop for selling, will that make me trade too often ?
3% stop loss is too low and a sudden drop of price may trigger the system to place Sell order. 10% profit is too high as this current market condition. If your aim is to trade more often, I suggest that you lower down your goal to place a Sell order for profit. In my case, once I reached a 3% profit, I sell right away and move to another trade.
I think 3% profit is not worth it of trade. In my opinion, 5% is better for a day trader. It's a decent aim to make profit and not difficult to get at the same time as the current volitality of crypto market is huge.
