MACD, EMA, Stoch, RSI, and many others are already built-in metatrader. All you need to do is attach them to chart by either double click or drag it to chart.

Or you actually need a combined indicator? like it'd show 1 if it's buy or -1 if it's sell. I think there's no much use of this anyway, since you can easily read the 4 indicators. You should, as being able to read multiple indicators professionally is the way to go with manual trading.

If you'd like to manually confirm new signal, you can by configuring expert settings. See screenshot
