Forex Expert Advisor/Robot mt4

I need a robot that open position buy and sell without need a signal. for example; if position buy touch the TP (TP = 20 Points), buy will open again with the same lot, it means sell position still open (sell 1), then after 50 points from sell 1, the robot will open sell 2 with double lot (like, sell 1; 0.01, sell 2; 0.02, sell 3; 0.04), after sell 2 open, TP of sell 1 will change and same to TP sell 2, but TP of sell 2 is 35 point NOT 20 point. illustration like below which the graphic go to up

if the condition like the table, buy position always open after touch TP 20 points. the same way will happen for buy position (buy 1, buy 2, buy 3) like the table  if the graphic goes down
