Option analysis and tooling is now improved on OpenMarket First: the GEX heatmap is now more accurate, and you can pick how it computes. Two modes: Dealer flow (new, the default): dealer positioning measured from the tape. Open interest (classic): the standard convention, dealers long calls, short puts. How the measured mode works: Every options trade has an aggressor and a quoter. Whoever crossed the spread is the customer. Whoever was quoting and got hit is the dealer. So every trade tells us what a dealer just took on: you buy a call, some dealer is now short that call. We add that up, trade by trade, contract by contract, and keep a running picture of what dealers are actually holding. Giant prints don't fool it. A block 25x the normal size is almost always two institutions moving a position between themselves, not a customer trading against a dealer, so it barely counts. The totals get sanity-checked against open interest every day (our estimate can't hold more contracts than actually exist), and when a contract expires, its position leaves the books, same as real life. And when we can't see enough, we say so. If our tape covers less than 60% of a contract's open interest, we don't pretend: that contract uses the classic assumption instead, and the chip on the chart shows exactly how much of the board is measured vs assumed. The two are never mixed inside one contract. In classic mode, a "wall" is just the strike with the most contracts outstanding. In dealer flow it's the strike where dealers actually have the most to hedge. Usually the same. When they differ, the measured one is the one that moves price. The rest of the update: Double-click any options panel and it takes over the chart. The IV smile expands to show every expiry with its date, the GEX curve gets a live readout of flip, walls, and totals. Drag the sensitivity slider and the heatmap re-colors under your cursor. No reload, no flash. The blocky look is gone: the surface now blends smoothly between strikes. Six new themes for every options panel, new heatmap palettes, and a little legend on the chart that always tells you what the colors mean. Live now.

TradingView can't replay the order book. It can't even rewind. Today, we are releasing Market Replay. In the clip, we replayed yesterday's CPI print release tick by tick. They replay the chart. We replay the market. It allows you to jump back in time and replay every candle, every order book tick, every liquidation, exactly as it happened. Pick any moment from years back. Scrub it like a video. What you will see is exactly what a live trader saw at that second. Here's what's inside: • The full order book, replayed. Rebuilt second by second at tick resolution: walls stacking, getting pulled, getting swept. • A real scrubber. Drag anywhere, both directions, instantly. Pause, step, or play at ten speeds from 0.25x to 30x. • Honest playback. Speed changes how fast you watch, never what happened. • Live data is gated out during replay. Replay is the only thing painting the chart. • 71 indicators replay in sync: CVD, open interest, funding, liquidations, footprint, volume delta, TPO, session profiles, VWAP, long/short ratios, ETF flows, dominance. • Your own scripts replay too, including ones built on orderbook and orderflow data. • Watch candles form: a 4h candle builds update by update, and at tick resolution second by second, with the book moving behind it. • Depth and liquidity readouts show the book as it stood at that moment, not now. • Years of candle and indicator history. Jump with the calendar or click any candle. Add an indicator mid-replay and it joins the timeline.
