Scalp Pin + Engulf (Ramesh)

How to apply as indicator

In TradingView, open Pine Editor.

Select New → Blank indicator (or clear the editor).

Paste the entire script above.

Click Save, then Add to chart.

You should see:

Green triangles under bars = bullish pin bar at support with trend

Red triangles above bars = bearish pin at resistance with trend

“ENG” labels = engulfing confirmation after pin

From here we can re-add the “fast single-bar reversal” piece once this base version is confirmed working on your chart.
