build an ea — 4

I want an ea that will reopen forex trades when they close due to reaching their take profit.

I also want an ea that will put on another buy trade when it reaches its take profit, and at the same time will put on a sell trade. I need to be able to tell the ea the size of position for the buy trade and to set a larger size of position for the sell trade. e.g. If the take profit for a buy trade of 0.02 is set at 0.70000, then when the take profit is reached, the ea will set another buy of 0.02 and at the same time will set a sell trade at 0.03.
I need to tell the ea when to take profit for the buy and to set the position sizes for the buy and the sell, and to set the stop loss and take profit for both buy and sell. When the price falls, i then need to ea to do the reverse and place a sell trade when it reaches its take profit also instantaneously placing a buy trade.
