Question 1

What is GammaTape?

Accepted Answer

GammaTape shows today's call wall, put wall and zero gamma for SPX, NDX, SPY and QQQ 0DTE options, mapped to your ES and NQ futures charts, from $24 a month.

Question 2

I trade ES & NQ futures, not options — is this for me?

Accepted Answer

Yes. ES tracks the S&P 500 (SPX) and NQ tracks the Nasdaq-100 (NDX). GammaTape computes the options positioning of SPX & NDX and maps every level onto your ES/NQ chart, so you read dealer gamma exactly where you trade.

Question 3

What is GEX, and why do these levels matter?

Accepted Answer

GEX measures how much market makers must buy or sell to stay hedged as price moves. Where dealer gamma is large and positive, they hedge against the move, which dampens it; where it turns negative, they hedge with the move, which amplifies it. That hedging is concentrated at a few strikes — the call wall and the put wall — and changes sign at the zero gamma, so many traders watch these levels as potential support and resistance. GammaTape shows where they are for the session; it does not predict what price will do there.

Question 4

Where do the levels come from?

Accepted Answer

From live 0DTE (same-day expiry) option chains. We compute gamma exposure (GEX), call/put walls, zero gamma, max pain and convexity ourselves — nothing is taken on trust — and update them through the session.

Question 5

How do I get the levels on my chart?

Accepted Answer

Two ways: the web dashboard (live, history and full session replay), and — on the Max plan — a MotiveWave extension that draws the walls and a net-GEX profile directly on your ES/NQ charts.

Question 6

Are the MotiveWave levels different from the website's?

Accepted Answer

Same engine, same walls — but read them carefully. The website charts SPX/NDX in index points; MotiveWave (with Align on) draws those levels on ES/NQ after a basis shift, so the Y-axis numbers are futures prices. Match Weight on both sides (OI is the default). Live tip updates about every few seconds on both.

Question 7

Is the data real-time?

Accepted Answer

Yes — every plan streams live from the open: the chart and the levels move on their own. Past sessions are there too, replayed minute by minute: 30 days on Starter, 90 on Pro and Max.

Question 8

Is there a free trial?

Accepted Answer

No free plan and no trial: every plan is live from the open. Starter carries the OI book and the GEX read on one chart with 30 days of replay; Pro adds the volume book, every read and two charts; Max draws the same levels inside MotiveWave. Your price stays yours for as long as you keep the subscription, and every first charge is covered by the 7-day refund policy — the prices are on the pricing page.

Question 9

Which instruments are covered?

Accepted Answer

SPX, NDX, SPY and QQQ. SPX and NDX map to ES and NQ for futures traders; SPY and QQQ are there for cash and ETF traders. Each runs from its own 0DTE chain.

Question 10

Is this financial advice?

Accepted Answer

No. GammaTape is an analytics tool: it shows where options positioning sits. What you do with it is your decision, and trading involves risk.

Question 11

Can I cancel anytime?

Accepted Answer

Yes, anytime: Settings → Subscription → Cancel subscription, a short flow that ends with Stripe asking you to confirm. Your access stays active until the end of the paid period. See /refund for the 7-day refund policy.
