I've noticed this works different on different brokers platforms too (even though the ones i've tested on have been all mt4), i've tested it a couple times, only a new trader too, but I've noticed it works best on the gomarkets platform.
I have retraced the steps as far back as the lines have been painted to and the minimum amount of pips on a single line has been 42. Therefore I have been basing my latest trades on at what point i have entered my order and put a TP at 40pips above/below where the new line has painted. Even though they say prior charts are not an indication of future possibilities bla bla bla
If this proves to be profitable I intend to up the lots and keep on makin that cash money.
Gotta make that cash money bitchez
