Stop loss is one of trading's most useful tools. Personally, I lost a substantial amount of money just because I was in a shoulder-free business. Unfortunately, choosing the right stop size is particularly difficult now because market manipulators simply knock out the stops with some actions. However, even if this factor is taken into account, it is impossible not to use such a useful tool, because without using it you will surely lose more. Stop loss minimises your risk and the likelihood of error.
My problem is the opposite. It seems like every time I try to use a stop loss, the coin will dip and sell at the price and then immediately go back up and trade for the price I was originally wanting to sell for anyways. It drives me nuts knowing I would have had the trade go through had I just not used a stop loss. I just don't really find them that useful if I'm trading top coins. Usually, even if the price dips down, it returns sooner rather than later to the price I was wanting to sell at.
sometimes I also experience the same thing, when the cut loss prices go back up, but I apply 10% to the cutloss, and according to my experience it's better to lose 10% and it will be easy to recover, than I did not cutloss and lose more than 50%.
