Development of Expert Advisor for Grid System for MetaTrader 4

Hi Developer,

I'm looking for someone with experience in MT4 and Grid System. 

Things to consider

System will operate in EURUSD

System will only be one sided (either buy or sell)

Grid should be every 50 points; 1 point being the fifth decimal number. Example:  BID 1.23750,  0 being a Point.  So I would want grid at 1.23750, 1.23800, 1.23850, 1.23900 and so forth.

Starting price will be entered manually. 

Lot size will be entered manually and will be the same for all orders. 

If I'm buying, I would like 90 opened buy stop orders, again, every 50 points. 

Trake Profit will be 50 points for all trades.

Slippage to consider on opening or closing trades should be 1-5 points. 

If a position is closed because it hit Take Profit, it should be reopened as a buy limit. For example, Price is at 1.23750, and first trade is at 1.23800 with take profit of 1.23850. If price goes to 1.23950, system should open buy limits at 1.23750, 1.23800, 1.23850, 1.23900.  If, for some reason, there is a limit of how many opened orders there can be, the opened orders closer to price should take preference. 

I would like EA to have StopLoss, which would also serve as a REVERSAL point.  So Buy Limit orders would be open until reaching such StopLoss. If price hits StopLoss, all buy stop and buy limit orders should be canceled, all opened positions should be closed. And it should automatically open sell limit and sell stops. I would like to enter StopLoss/Reversal point at start of trading but it should also be able to change mid trade, and all opened orders conflicting with StopLoss point should be closed. I would also like EA to send EMAIL Notificacion if StopLoss/Reversal is hit. 

Example: I believe price is going to go up. Price is at 1.23742. I manually select grid to start at 1.23750. I manually select lot size at .05. I manually select StopLoss at 1.22600.  Buy stops should open at 1.23750, 1.23800, 1.23850, so forth. Buy limit should open at 1.23700, 1.23650, 1.23600 and so forth until 1.22650. If price reaches 1.22600, all buy limit, buy stop and opened orders are closed and automatically system opens sell stop at 1.22600, 1.22550, 1.22500 and so forth, and opens sell limit at 1.22650, 1.22700, 1.22750.  If price continues going down, and reaches 1.21300, I might want to change StopLoss/Reversal point to 1.21800. After selecting new StopLoss/Reversal point, sell limit order at 1.21800 and all sell limit orders higher than 1.21800 should also automatically close. 

There should be an option to close all opened trades and also another option to close all opened orders with the click on a button. 

EA should work properly on demo, real account and Virtual Terminal with Virtual Hosting so there are no connection failures.
