dear sir,

please expalin the difference in each of the courses on definedge platfor. i am confused between 3 or pathshala or even some times pnf gurukal one. please guide

sir in many momentum studies including hagdish and titman last 20 days return shoudnt be included in returns calculation as 20 day momentum is mostly mean reversion kind of thing. theres no option to discard the last 20 days returns. please look into that

i too have noticed the same. reason could be different data on which baktest has been done. most probably data isnt clean
