open trade with martingale method

[shawnlim1]

Hi,
i want create a EA that help me create 7 pending order with 20pips distance each pending order and with double lot size on each pending order. for example:

I place an buy order on price 100.100 with 0.01 lot size then EA will place 8 pending order on 100.080 with 0.02 lot size,100.060 with 0.04 lotsize, 100.40 with 0.08 lotsize,....and so on .

Besides that when every pending order is open then all open trade must modify TP to the newest open trade plus 20pips. After the TP is trigger then all pending order must cancel.

Please help....
