EA to enter trades based on Heiken Ashi and manage trade with stop

Hi, I'm after an EA to enter and manage trades based on Heiken Ashi direction/colour change with management of trade with initial fixed stop moving to trailing stop at given profit level.

Platform - MT5.
Trade volume, timefame, trading hours and currency/index to be adjustable (Plan is to intially use this on GBP/USD, MT5 spread bet account, hourly timeframe, EA operating hours 0700 - 2000 hours GMT).

Entry for buy/sell based on Heiken Ashi direction/colour change.
On entry initial stop to be placed at 15 pips loss.
Once price moves to 10 pips profit stop to move to break even and then trail stop at 10 pip intervals.
Open trades to be closed when EA reaches end of set operating hours.

I doubt very much that the EA would generate a signal whilst a trade was open based on trading times and nature of the trailing stop however this could happen in a flat or tight range market.
That’s said if there is a signal/entry while existing trade is open then existing trade to be cancelled and new trade put on in direction of change as normal circumstances.

If I manually close a trade EA to continue as normal only entering trade again once there is a signal from change in Heiken Ashi.

EA source code to be provided and there to be clear marking/commenting allowing me to edit currency, timeframe, trading hours, trading volume, initial and trialing stop level.

Heiken Ashi indicator used is is Heiken_Ashi.mq5, file attached. Image attached showing 2 signals, a buy and sell entry based on hourly signal, change in Heiken Ashi prompts entry on new hour candle.
