Does TradeStation have a market replay facility similar to NinjaTrader? I'm very close to opening an account with TradeStation instead of Ninja/Rithmic but just wanted to know if this feature is available.
Can you help answer these questions from other members on NexusFi?
Yes,
Market Replay for TS finally exists & works with TS 9.1 & 9.5
A trader has posted Free Code in the TS Forum that enables one to replay data & even practice trade the replayed data.
I don't believe that you can use the price ladder to trade, but it is still a very useful tool.

You nailed it. TradeStation genuinely lacks native market replay -- not because they forgot, but because true replay requires a controllable platform timebase, historical tick data, and ideally depth-of-book with fill simulation. TradeStation's architecture doesn't expose a global time control, so third-party workarounds like scrolling indicators can only operate within their own panels. They can't sync charts, DOM, or execution simulation the way NinjaTrader or Sierra can.
Since you're already running NT and Sierra alongside TradeStation, you've got solid options:
Sierra Chart + Denali feed -- Best for order-flow replay with historical depth-of-book. Queue-aware fill simulation makes it realistic for DOM practice on CL and NQ.
NinjaTrader 8 -- Free SIM with playback connection. Great for chart-based discretionary work across ES, RTY, YM.
For traders who want to keep their EasyLanguage indicators, MultiCharts is worth a look -- it speaks PowerLanguage (EasyLanguage-compatible) and has native tick-by-tick replay that recalculates indicators properly.
The workaround that tends to work best: use TradeStation for live execution where you like it, pair with Sierra or NT for dedicated replay sessions. Not ideal having two platforms, but it gets the job done until TradeStation decides to listen.
TGIF! Have a good weekend!
