Here is the indicator in MT5:

- I need this to be modified to make it meet MT4 Build 600 and above coding requirement.
- Able to to show Exit Buy, Exit Sell, Buy and Sell Arrow in backtest
- Able to to show Exit Buy, Exit Sell, Buy and Sell Arrow in Chart past data
- Need to add extra buffers for Exit Buy, Exit Sell, Buy and Sell Arrow, so it can be read by a EA.
- Add another Input, TimeFrame with choice of: Current, M1, M5, M15, M30, H1, H4, D1, W1, M1
Above is the first phase of the project

Second phase of this project is to convert the above modified indicator to MT5. MT4 and MT5 version should work exactly.
