short term trading means we take the risk, lose or profit. even those two things often happen, because no trader can analyze correctly for each transaction, so doing a cutloss is a common thing, not if the analysis is wrong then we become holders of daily trading, but of course the accumulated profit will be greater than the loss
Short term trading with proper stoploss may help still you must need strong technical analysis. But, planning up short term trading only by weekend may not help because, in my experiences, you need to be a full time trader if you target short term trading. For long term trading you can be an occasional trader.
