MT5 EA

I need an EA that will work like this:

1. i add it to the desired chart and a simple pannel will be displayed onto the chart in one corner.

2. ea will open new position every time a new candle is opened.

3. in the pannel i can switch bias from short to long only so the ea will trade only in a direction unless configured otherwise.

4. if i change the timeframe it must update to that particular timeframe (if the chart is on 5m when i add the EA, then want to switch the chart to 1h, the EA will open future positions on new candle open on 1h without me being required to update anything in the ea config).

5. it will have a lot size setup, and optional trailing stop and step setup, SL and TP.

6. it will not open new positions on new candles open if the previous position has not been closed.

Thats all, no indicators or any trading logic.
