in some cases we might find that when we trade and follow the major trend, often the minor trend or the trend in smaller time frame needs some more time to consolidates the price in order to have the same trend with the major trend, it happen some times and when we are sure that the major trend is still strong and we have a big opportunity to gain profits i think changing our stoploss level is still ok and fine as long as the amount of the stoploss we are setting is still reasonable and still under control, as a trader we need to adapt and really react with the market condition carefully and i think adding more stoploss level or even cutting our loses short is an attitude and also habit we need to have because as a trader we need to react correctly and taking some decision based on the real market conditions as a trader we need to be flexible in taking some corrective measurement i order to gain profits and making our trade much more profitable and less risky,
