How to apply Price Density indicator?
In my experience, more filters and indicators would be needed to temporarily stop trading. In this case, I do not mean closing already open positions, but stopping the opening of new ones.
-Stop the opening of the 1st position,
-Stop Martingale etc.
For example Price Density - Market Noise Index indicator (https://www.mql5.com/ don't trade above value) and similar that would temporarily stop trading.
You can already use any signal / filter / custom indicator to enable/disable first entry, martingale or hedge.
You can even activate each signal on some event, like DD or trades number.
What else do you need to bring your idea to life?
