Development of a triple EMA scalping EA for the 1 minute timeframe

Hello, I need an forex scalping EA that  works in the 1M timeframe and uses 3 EMAs (e.g. 50, 150 and 200. The periods should be included as variables).

The EA should open a buy (or a sell) position, if the following conditions are met:

  - The trend direction is clearly* upwards for buy or downwards for sell.

  - The chart is creating a pattern as shown in img1(buy condition) or img2 (sell condition).

This EA should not use martingale, grid or other risky strategies - scalping itself is risky enough.

Please make me suggestions for placing stop-loss and take-profit levels and how it's usefull to modify them with help of the EA during the trade (using dynamic SL and/or break even points).

If you think, it could be usefull, please implement an "hide stop-loss and take-profit levels from the broker" option.

The EA should have an option to trade only in a certain time window (e.g monday - friday from 1:00 am to 6:00 am).

*"clearly upward trend" defined as 50 EMA > 150 EMA > 200 EMA and the slope of each EMA > +30 degree and "clearly downward trend" defined as 200 EMA > 150 EMA > 50 EMA and the slope of each EMA > -30 degree. 

Thank you in advance
