A truth said by Xray bro.....
Systematic trading consists of rules for Entry,SL,TSL and Exit, since it is rule based there will be no emotions at the time of entry nor any confusion of analysis , Discretionary on other hand depends on trader own mind set,even there are rules for Entry,SL,TSL,and Exit are defined..just a clause is added If... or But,Only very few can cope with that..that too with limited qty,i was a discretionary in the initial stages where my qty was limited ,with no scope to rise,Once turned to systematic way of trading volume growth was seen !!!
Fear factor at draw down phase in systematic trading ,will push us to tweak the method or jumping unless it is backed by thorough back testing !!! ,This part is also covered by very few...
