Last nights price action is a perfect example of the importance of correct risk management. All 3 entries taken last night ran to roughly 3% and then reversed.
Due to correct risk management all 3 of these trades resulted in Break even results instead of full losses.
Finishing the night at break even instead of -3% is not a huge difference $ wise but also a massive difference mentally.
By closing 0.25% of your position at 3% profit you are essentially Break evening your trading while still leaving your stop open and 75% of the position still running.
