Gamma Walls & Bias
Options walls · COT · open interest · footprintReads where the options market will push back. Big option positions sit at a few strikes. The dealers on the other side must buy and sell futures to stay hedged. Above the flip they trade against price, like a shock absorber: walls tend to hold. Below the flip they trade with price, like a gas pedal: breaks tend to run. The indicator puts those walls on your chart and adds what the big money is doing.
- Each morning, copy the day’s block from the free MMM Gamma page and paste it into Paste Daily Block. It holds today’s strikes (0DTE) and the 90-day walls.
- The indicator draws today’s call wall (the ceiling), put wall (the floor) and flip, plus the 90-day walls, zero gamma and the magnets. Index levels (SPX / NDX) are turned into ES / NQ prices for you.
- MARKET tells you the type of day: CALM when price is above the flip (walls tend to hold), FAST when it is below (breaks tend to run).
- BIAS reads the last month, week and day candles and checks yesterday’s open interest (new money in or out). MONEY adds the weekly COT: what asset managers and hedge funds are doing.
- At a wall a signal prints: Wall Held, Trap, Break or Fake Break, graded A, B or C by how many checks agree. Hover it to see where the idea is wrong and where the job is done.
- DO turns it all into one line, for example “Buy dips at floors” or “No bias · stand aside”.
Best for: ES / NQ traders who want the day’s ceilings and floors before the open, and want to know if it is a day to fade the walls or to follow the breaks.
Research only, not advice. The gamma signals are not part of the tested MMM strategies. Watch them on your own chart first.
| Call wall today | Deep blue, thick. The strike with the most call gamma today: the day’s ceiling. |
| Put wall today | Orange, thick. The strike with the most put gamma today: the day’s floor. |
| Flip | Purple. Where dealer hedging changes side. Above = CALM, below = FAST. |
| Call / put wall 90D | Green / red. The big walls for the next three months. Leave them at 0 and the indicator estimates them. |
| Zero γ 90D | Black. The 90-day flip. With no paste, a 90-day VWAP estimate takes its place. |
| Magnets | Grey dotted. The next biggest call strikes: price is often pulled toward them. |
| Plan line | Dotted. Today’s plan from yesterday’s candle and its open interest. |
| Histogram | Gamma by strike, 3 candles right of price, always between price and the labels. Green = calls, red = puts. |
| Signals | Wall Held · Trap · Break · Fake Break, graded A / B / C. They delete themselves when the idea is wrong or the job is done. |
| +120 | Each level shows its distance from price in points. Turn on Show Prices to add the price. |
| Your style | Every line has its own color, width and style. Lines can start where the level was born, at price or at the histogram. |
