EA based on SAR-RSI & EMA

Hi,

I need someone to create an EA to open & close trades based on a strategy composed with Heinki Ashi, parabolic SAR / EMA 200 & RSI [scalping strategy]. EA for MT4

(the strategy is explained in details here : https://www.youtube.com/watch?v=zqUC8dtPphI >> 10 min).

The EA can open only 1 trade per currency.

I'll need some parameters :

- Money Management :

-- lot size,
-- stop loss in €/$ 
-- TP : in €/$ 
-- Equity protection : in %   (stop trading and close all trades when equity goes below this value))
-- trailing stop to secure the trade if needed : 
--- traling start € or $
--- step in € or $

- symbol suffix  (Vantage add a "+" to the currency symbols)

- new filter based on Investing for ex (to avoid trading if Big news expecting)

- max spread : number (for ex : 6) >> to avoid to enter if the spread is too high. This is a scalping strategy.

If you need more explanation, feel free to ask.

Thanks for your help,
