Cross Indicators a b Delta

Hello

I need an Expert Advisor with the next issues.

Optimizable parameters:

- a: short period of the chosen indicator

- b: long period of the chosen indicator

- Delta: Delay or advance regarding to opening price

- SL: stop loss

- TP: take profit

- TF: Time Frame

Other parameters:

- Lotes: number of Lots

- INDIC: The EA must be able to work with 3 indicators: EMA, STOCHASTIC (only %K) and TRIX. For instance, if the variable takes the value "EMA", the a and b parameters are referred to the Exponential Moving Average. On the same way for TRIX and STOCH (only the line %K).

The EA open positions acoording to the next criteria:

1. If short indicator crosses over the long indicator at the close of the last candle, it puts a BUY LIMIT or a BUY STOP according to the value of Delta. If Delta is positive, it puts a BUY LIMIT "Delta" points below the open price. If Delta is negative, it puts a BUY STOP "Delta" points above the open price.

2. If short indicator croses down the long indicator at the close of the last candle, it puts a SELL LIMIT or a SELL STOP according to the value of Delta. If Delta is positive, it puts a SELL LIMIT "Delta" points above the open price. If Delta is negative, it puts a SELL STOP "Delta" points below the open price.

3. If a position short (long) is open, the event 1 (2) results in a double LIMIT or SELL order, one for the (possible) close of the open position and the other for the open of a long (short) position. 

4. If there isn't any position, the event 1(2) results in a single LIMIT or SELL order.

The EA must provide in mql5 language, open source.

P.S.: Important!!! The EA must be easiest as possible, no money management or other features that the above.
