NoVo Dealer Levels for TradingView

How it works

Four numbers, typed once. About fifteen seconds.

1. Open SPY, QQQ or IWM and note the gamma flip, call wall, put wall and expected move.
2. In TradingView open Pine Editor, paste the script below, and click Add to chart.
3. Open the indicator's settings and type in those four numbers.

The levels on those pages are delayed. The live map, recomputed every 5 minutes with net GEX, gravity and the written read, is Trader.

What it draws

The gamma flip, call wall and put wall as labelled lines; the expected-move band shaded around the spot price at the time of the read; and a faint background tint for which side of the flip price is on. Above it dealer hedging leans against the move; below it runs with it.
