Replikanto can be used with Playback NinjaTrader connection?

Yes — starting with NinjaTrader 8.1.7+ and Replikanto 1.6.1.8+, Replikanto can be used with Playback connection mode.

Version Requirements

To use multiple Playback accounts with Replikanto, you need both:

• NinjaTrader 8.1.7 or later — Introduced Feature #31845: Multiple Playback Accounts
• Replikanto 1.6.1.8 or later — Required for Replikanto to work with multiple Playback accounts

What Changed in NinjaTrader 8.1.7+

NinjaTrader 8.1.7 introduced Feature #31845: Multiple Playback Accounts, which removes the previous limitation. You can now create and manage separate Playback accounts to simulate trading more realistically.

How to Use Multiple Playback Accounts

To use multiple Playback accounts with Replikanto:

• Enable Multi provider mode: This setting must be enabled to add additional Playback accounts
• Create separate accounts: Set up different Playback accounts to test strategies, assign instruments across accounts, or mirror real-world setups
• Select accounts during Playback: Playback accounts can be selected anywhere account selection is available

For Older NinjaTrader Versions

If you're using a NinjaTrader version older than 8.1.7, Playback mode only provides a single Sim account (Playback101). In that case, use the Simulated Data Feed connection instead, which allows multiple Sim accounts for testing.

Refer to the official NinjaTrader guide for setting up multiple simulation accounts:
