Trend following Indicator and EA based on EMA cross

Hi 

I am looking to engage with a programmer to create a trend following, EMA cross based Indicator and accompanying EA

Indicator requirements:

Based on two adjustable EMA lines 

Buy signal when EMA crosses above

Sell signal when EMA crosses below

EA requirements:

Adjustable entry based on the close price of the previous candle 

Adjustable stop loss 

Adjustable take profit level, at which point a trailing stop loss is engaged

Adjustable trailing stop loss

Re-entry based on an adjustable percentage of previous high and exit of the TSL. Previous high needs to be adjustable to allow for x number of previous candles  

Once re-entry occurs, the process needs to repeat from the adjustable stop through to the re-entry conditions.

Repeat until indicator signals reversal

When the indicator signals for a reversal of the trade, any current open positions need to be closed

Additional requirements: 

All orders need to be limit orders

If order isn't filled by the close of the candle then close order and open a new order based on the EA entry conditions

Signals from the Indicator need to be based on real time data rather than closed and confirmed candle data, to give the quickest entries

The ability to take more than one entry per candle, however not more than one entry at any one time, unless in the opposite direction
