Update on yesterday's trade:
I left it opened overnight (with a wide stop loss – 130 pips) and this morning closed it with a 22 pips profit – it may be more if I left it open, but I don't want to follow charts any more).
From now on I'll follow the system.
There are few reasons for this decision:
Yesterday I could have taken similar profit (20 pips with risk of 20pips instead of 22pips risking 130pips)
I could have taken that profit in about 30 minutes instead of all day chart following, risking massive amount of pips, leaving trade opened overnight, stress etc.
My current style is a short time break out strategy, not trend following.
There are some traders who are very successful in trend following strategies and I may do it one day once I know how to analyse charts properly.
For now I'll stick to original system, test it with small trades, no chart following all day, no analysis paralysis, no stress, acceptable risk (20pips) etc.
