Best stock market replay simulators (2026)
A stock market replay simulator plays back recorded market data from a past day so you can practise trading it as if it were live. This roundup, written by the makers of Hindsight Markets, compares replay tools that stock traders look at: what each one replays, how far back it goes and who it suits, from each product’s own site in October 2026.
How we compared them
Everything here comes from each product’s own website, in October 2026. Plans and prices change, so check each site before you choose. We make Hindsight Markets, and we say where the others fit better.
The tools do different jobs. Some replay one chart at a time, some replay a whole session, some are built for forex and futures first, and one replays the order book you recorded yourself. The right one depends on what you trade and what you want to practise.

The tools, one by one
Hindsight Markets
A whole trading platform on a real past day. Every stock, ETF and warrant listed on a US exchange replays together from the 4:00 a.m. pre-market to after-hours, and you switch symbols at any time on one account. Scanners rerun every minute with only what was known then, news and SEC filings arrive when they were published, Level 2 shows the book exchange by exchange, and your orders fill against that day’s displayed size and queue, under that date’s halt, LULD and short sale rules. The journal takes you back to the moment of any trade.
Keep in mind: the days start in August 2026, so the library is young; it is US stocks only; and it replays one day at a time by hand, so it is not a backtester for years of data. More on the stock replay simulator page.
TradingSim
A simulator in the web browser that replays full market sessions: several symbols on several timeframes, scanners with float, gap, pre-market volume and short interest filters, and time and sales, all synced to the replay clock. Level 2 by venue and tick and second charts are on its Premium plan, which also trades live sessions on a 15-minute delay. History is two years on Pro and five on Premium, and it covers US stocks, futures and crypto, with a 7-day free trial.
Best for: day traders who want years of past sessions in one tool. See how it compares in detail on our TradingSim comparison.
TradingView Bar Replay
A replay built into TradingView’s charts: pick a point and play the bars forward, with several charts synchronised in time and a replay trading mode on the chart. On Essential, one-minute data reaches back 6 months, a year on Plus, and all stored history on Premium and up; seconds data starts in August 2022, and tick data covers the last 7 days on Ultimate. It runs on web, desktop and mobile apps, across many markets.
Best for: chart traders who already live in TradingView. See market replay compared with bar replay.
thinkorswim OnDemand
Part of Schwab’s thinkorswim platform. Schwab says OnDemand lets you replay any trading period from the last several months and test your skills with simulated trades based on that data.
Best for: Schwab clients who want to practise in the same platform they trade with.
FX Replay
A web backtester where you replay charts and trade bar by bar. It covers forex, futures, indices, metals, energy, stocks, crypto and agricultural markets. Stock and futures data and seconds-level intervals are on its Pro plan; a free Beginner plan has a couple of sessions to try it.
Best for: forex and futures traders, and stock traders testing a chart strategy by hand.
Forex Tester Online
A manual backtester in the browser. It offers tick-by-tick history of up to 23 years depending on the asset, across forex, stocks, indices, futures, commodities, ETFs and crypto, with a selected list of stocks that grows on its higher plan. There is a free demo.
Best for: traders who want decades of history to backtest a forex or index strategy by hand.
Bookmap
An order-flow platform that draws the order book as a heatmap. Its record and replay feature, on Digital Plus and higher plans, plays back sessions you recorded tick by tick with full market depth. Backfill depends on the data provider, such as 72 hours from BookmapData, and stock data is bought separately from a provider.
Best for: traders who study liquidity and order flow in the book.
MultiCharts
A desktop trading platform whose simulator plays back historical data tick by tick, second by second, minute by minute or day by day, with all symbols synchronised by time. While it plays, you can place orders, trade from the chart, use the DOM and run automated strategies. Level II and depth of market are supported in playback when the historical Level II data comes from your data provider or is downloaded. MultiCharts lists the simulator as free.
Best for: experienced desktop traders who bring their own data feed and want to test automated strategies as well as trade by hand.
Webull chart replay
A replay of one symbol’s quotes on a day you pick from the last month, inside the Webull app, at speeds from 1x to 120x, with a progress bar to drag through the day.
Best for: a quick look back at how a recent day played out on a stock you already follow.
Live paper trading is a different thing
Paper trading accounts let you place simulated orders against today’s live market. thinkorswim paperMoney, Webull paperTrade and moomoo paper trading all describe practice with real-time market data, and they are a good way to learn a broker’s platform before you trade it. They do not replay a past day, so you practise only while the market is open and only on the day you get. A replay gives you the morning a stock actually ran, whenever you have time.
The honest limits
Every replay simulator simulates your fills, and none can tell you exactly what the same order would have done with real money. In Hindsight Markets, off-exchange and hidden liquidity never fill you, and your own order does not move the market after it fills. The full list is on the disclaimer page. The glossary explains Level 2, time and sales and slippage.
Common questions
- What is the best market replay simulator?
- It depends on what you trade. For small-cap stock day trading on a whole market day, Hindsight Markets. For years of stock sessions plus futures, TradingSim. For charts in any market, TradingView Bar Replay. For forex and futures backtesting, FX Replay; for long tick history, Forex Tester. For order flow, Bookmap.
- Is there a free stock market replay simulator?
- Some tools have free ways in: FX Replay has a free Beginner plan, though its stock data is on Pro, Forex Tester has a free demo and TradingSim a 7-day free trial. Plans change, so check each site for the current terms.
- What is the difference between market replay and paper trading?
- Paper trading places simulated orders against today’s live market. A market replay plays back a past day, so you can practise at night or on weekends and take the same morning again.
- How far back do replay simulators go?
- It varies widely: from the last month on Webull’s chart replay, to two to five years on TradingSim, to all stored minute history on TradingView’s Premium plan and up, and up to 23 years of tick data on Forex Tester. Hindsight Markets opens every trading day from August 2026 forward.
- Can you replay Level 2 in a simulator?
- Yes, in some. Hindsight Markets replays the full book exchange by exchange on every day it has, TradingSim shows Level 2 by venue on its Premium plan, Bookmap replays full depth from sessions you recorded, and MultiCharts plays back Level II when your data provider has it.
- Does Interactive Brokers have market replay?
- Interactive Brokers’ own pages say a chart can be played back candle by candle in classic TWS charts, though not in TWS Advanced Charts or IBKR Desktop, and its paper trading account fills simulated orders on real-time quotes. For a replay of the whole US stock market with the book and the tape, Hindsight Markets is one option.
