What is On-Submit vs On-Fill Replication?
On-Submit replication mirrors resting limit and stop orders to follower accounts the exact millisecond they are placed on the master account, whereas On-Fill (Entry/Exit Market Sync) waits until the master executes before dispatching instant market orders to follower accounts.
Mathematical Calculation
With 1:1 Bracket Sync, resting limit and OCO stop brackets sit natively on the exchange for pure futures routes. With Entry/Exit Market Sync, followers execute market entries and exits when the leader fills—solving cross-market price discrepancies between Futures and Forex/CFDs.
Real-World Numerical Simulation
Choosing Between 1:1 Brackets and Entry/Exit Market Sync
Scenario A (Tradovate to Tradovate / AMP Futures): Both accounts share the exact same CME tick feed. Use 1:1 Bracket Sync so atomic OCO Stop-Loss and Take-Profit orders rest natively on the exchange.
Scenario B (Tradovate NQ to MT5 US100.cash CFD): Because NQ futures and US100 CFDs trade at different dollar prices (basis spread), copying a hard NQ stop price would fail or stop out early on MT5.
The Solution: Enable Entry/Exit Market Sync on the MT5 follower—the millisecond the Leader enters or exits, the follower fires an instant market order, bypassing price level differences completely!

Institutional Comparison Matrix
| Replication Mode | Execution Mechanism | Price Discrepancy Immunity | Best Used For |
|---|---|---|---|
| 1:1 Bracket Sync (Native OCO) | Mirrors Entry + hard SL/TP price levels | Requires identical underlying feed (Futures <-> Futures) | Tradovate <-> Tradovate, NinjaTrader Cloud, AMP MT5 |
| Entry/Exit Market Sync | Fires Market Entry & Market Exit when Leader acts | 100% Immune to cash-futures price discrepancy | Cross-Market (Tradovate Futures <-> MT5 Forex/CFDs) |
