Sometimes it works, but as a trader, I learnt that you are also a risk manager, and you need to shield yourself for the worst outcome, always.
I personally don't, because holding a losing position outside my risk comfort level could potentially increase my losses unnecessarily, compared to just cutting my losses earlier.
Also, think about the funds you have used to open the position. Waiting for your position to break even away from a loss could take days, months, even years. This means you can't use these funds to invest in better setups you might find.
As you go through the BabyPips course, it will explain these concepts so you can avoid burning out your account on the get go.
