Simple EA based on existing indicators

I am proposing you to build a MT4 EA with the following requirements:

1. Work with all symbols and timeframes.
2. Given the buffers from custom indicators of type:
1. DRAW_ARROW buffer
2. DRAW_LINE 1
3. DRAW_LINE 2
3. Indicator settings will be shared via Chart template.
4. EA inputs
1. Risk % - default to 1.
2. TP - default to 100.
3. Trading start time - default to 0  - seconds elapsed since day start
4. Trading end time - default to 86400 - seconds elapsed since day start
5. Trade only between Trading start time and Trading end time. The time is specified in seconds in order to be able to use tester optimization.
6. Use position sizing based on the account balance. Setting the lot size to the Risk % in case stop loss is hit and in the range of MIN_LOT > MAX_LOT.
7. On new candle,

1. take a BUY position if arrow is set on previous candle and indicator lines are trending up. Set SL to the LOW from the previous swing low
2. take a SELL position if arrow is set on previous candle and  indicator lines are trending down. Set SL to the HIGH from the previous swing high

Thank you!
