Hello,
Thank you for the project invitation, much appreciated.
My name is Erman Ardie. I've review your specification, and with the help of my 8 years experience, we can do it in 1-2 days and I put 3 days for spare.
One thing about your strategy though, the trading and trail stop should be based on real candle price. We can use Heiken Ashi's price as long as real candle's price is at the correct position to do the operation. Alternatively, we can use custom chart.
As for the additionals, I'd be gladly guide you.
Best Regards,
