Dilution of position in EA

Description and source code is in attachment.

When EA starts, it put buy/sell stop positions which it moves up and down.

When actual price touche stop position, position changes to standard buy or sell. 

Shortly after buy or sell position is established, I need establish buy or sell limit positions. Limit positions should have the same stop loss and take profit like the first position. I need set spaces in pips between limit positions and its own lotsize. I need three limit positions. I need manage long and short positions separately, like in actual source code.

When price will go wrong way, price touche buy limit, it change to buy and  dilute position.

All positions will have the same stop loss and take profit. In case after price hit the first buy limit and will go to profit, EA automaticaly moves stop loss and do trailing with stop loss. I need change stop loss according to the first trade at all limit orders. Long and short positions must be managed separately.

When price hit stop loss in profit, EA must close position and erase limit orders.

This logic can be with invisible orders. It depands what will be less laborious.

May be the case, when is low volatility on market, that EA establish long and short simultaneously.
