Martingale EA Needed Buy / Sell MT4

Specification

Hi guys,

I was hoping someone could help me create the following martingale EA.

The EA will be used mainly for gold. But possibly used on other pairs.

It will start off with a buy, when it hits TP (Or SL), it will then sell, when hits TP (Or SL) it will then buy and so on...

I need the EA to open a new trade and increase it lots sizes when it moves enough against the trade.

When a new position is opened, I want all open trades to change to the same TP as the newest one so they all close the same time (And in profit with the right settings)

I want an option to add in a SL, which stays at the same price as the first position, with every new open position. This is to mitigate the risk of blowing the whole account if it does go really bad. 

I want to have the options to controll the following.

Set TP - Change TP Value

Set SL - Change SL Value (0  = No SL)

Lot size multiplier - How much the lot sizes increase by (1 = Doesn't increase, 2 = doubles etc.)

Lot size - Starting lot size (0.01 as standard)

Step - Distance until new lot opens when trade goes against EA

The EA should be built so there is always a trade running (Buy or Sell) unless manually stopped.

Any questions please ask. I hope I have explained it ok. Happy to negotiate the price.

Thanks
