For God's sake, and in which way your emotions' control will save your cash from a market which moves against you for 200 pips in a matter of minutes or even seconds?
First you open a massive position, which might be the first mistake. You can be a scalper, and that would be fine, but in that situation you don't allow the market go against you for 200 pips when scalping. Or you can have another egy which allows you to have a market 200 pips from youpersonally, but in that situation you surely don't open a massive position (known as a % of your funding ).
And this can be PLANNING, not emotion management.
Yes, even in case you've got a massive position along with a market moves against you for 200 pips, yes, surely, you're feeling strong emotions! But going to control those emotions will not save your cash in any way. You can be as good as you like with controlling your emotions, but if you allow a drawdown of 200 pips for a massive position you are likely to lose your cash anyway sooner or later, regardless of your absolutely mastered plogical control.
You require a PLAN, a broadly back analyzed and forward analyzed one, and analyzed by yourself. A plan which gives you confidence that it's positive expectancy. You need this strategy to tell you exactly what to do in every market position (go long, go short, stay away) and the way to do it (entry, exit, position size, etc.). You then need the DISCIPLINE to strictly behave only in accore for this strategy.
