The secret shhhh is not targets. It is exits. No matter what you read, in the grand scheme, the market does not care about where any of us small retail traders put our exits individually.
Deciding where to take a profit is a nice problem to have. Amateurs (don't be one - for long anyway) focus completely on winning trades and positive "winning attitude" to their detriment.
Initially a trader has to decide where to get out ... if they are wrong about the trade. It is in no way being negative to think each trade might be a loser. Right from the start. Protecting trading funds is the first priority.
If instead the trade does turn into a profitable one next they have to have a place away from current price it needs to move against the current profit to decide now is the time to exit flat.
So either way, winner or loser it all comes down to where you are wrong. Initially or continuing with trade.
