i use stochastic cross overs with a custom finger pointing short and long positions, i want to add money management of 20 points whenever the finger points and it should automatically open the position for me and close based on the take profit or stop loss. i am learning mql4 language presently but it might take me some time to be able to do exactly what i want, so pending that i need help on this one. thanks guys help please !
