Are you feeling stuck in trading due to your strategy? The person you are thinking their strategy is working, may have a strategy that is not sustainable. While it is important to be able to unlearn and learn something you should be able to understand also sometimes that your strategy is not working because you have not gone deep enough in the mastery of it.
One other very important thing I have to add here is that whenever you are trying to explore or deploy another strategy from someone else, it could be your mentor you could first watch their trading size and their fundings I mean, their equity they are using to trade it could be that whenever such strategy is deployed due to your balance you may not be able to sustain that such positions for long before getting liquidated, therefore, before deploying any trading style we should first know our capacity based on our equity to trade.
