Market Replay overview

Market Replay plays a recorded market session back on your charts and DOMs. You can practice reading the market and placing orders when the market is closed. Orders are simulated and nothing reaches a broker.

Start Market Replay

  1. Click the signal icon in the top bar to open Connections.
  2. Find the Market Replay row. Its account line reads Replay 01 · Replay 02.
  3. Click Connect.

The session starts at the beginning and plays at normal speed. Open a chart or DOM on one of the replay markets and choose Replay 01 or Replay 02 as the account to trade.

Once Market Replay is connected, a replay pill with the replay clock in New York time shows up in the top bar. Click it to open the replay controls.

What you can practice with

SessionWhat it is
US Open sampleES, NQ and FESX from 09:30 to 10:30 NY. It includes three days of synthetic tick and chart history. It needs no file.
Recorded sessionA real market session that you recorded yourself or imported. See My recordings.

Replay accounts

  • Replay 01 and Replay 02 are the two simulated accounts for Market Replay.
  • They're separate from Server SIM, Firm SIM and Simulated Trading. Those accounts can't trade replay data.
  • Restart clears the orders, positions, fills and P&L of both Replay accounts.

Rules to know

  • Replay and live data don't mix. If a Rithmic connection is connected, Tradrr shows Switch data source and asks you to disconnect it before you start Market Replay. If Market Replay is connected, disconnect it before you connect a live account. Market Replay takes over chart and DOM market data while it runs.
  • Pick the session before you connect. To change the session, disconnect Market Replay first.
  • Jumping back resets your replay trades. See Timeline, speed and restart.
  • Everything runs on New York time. The clock on the pill is NY time.
