Fill price differences between your leader and follower accounts are almost always the result of broker-side execution — not a Tradecopia replication failure.
You might be experiencing this if:
Your follower account filled a trade at a noticeably different price than your leader
Your follower's P&L is lower than expected despite what look like identical trades
A position closed on your follower at a worse price than it closed on the leader
The fill difference seems worse during busy market periods or news events
Your risk manager triggered and the exit price was beyond your configured threshold
Check your broker order history first
Before investigating anything in Tradecopia, log into the affected follower account directly on your broker's platform and note the actual fill prices:
The fill price on the leader account
The fill price on each affected follower account
The exit price on each account, if exits were also affected
Tradecopia replicates the order instruction — once that instruction is sent, execution (fill price, exit price, and slippage) is entirely controlled by the broker. Checking the broker order history first establishes the actual fill data and usually explains the discrepancy immediately.
Common causes of fill price differences
Work through this table to identify which factors apply to your situation:
Factor | What to check |
Market volatility | Was the trade during a news event, equity market open, or another high-volatility period? Prices move quickly when many participants are trading simultaneously — fill prices shift between when the order is sent and when the broker executes it |
Tradovate API rate limits | Do you have many Tradovate accounts and trade at high frequency? Tradovate's API rate limits can introduce lag that affects execution timing across a large copy group. See How broker API rate limits affect trade replication |
TopStepX fill-based replication | TopStepX followers use fill-based replication — price differences between your leader and TopStepX follower accounts are expected by design. See How bracket and TP/SL replication works by broker combination |
Local machine or network | Are you running a large copy group on hardware with limited CPU or an unstable network connection? High resource load can delay order processing. Pro desktop only — Pro+ Lite and Pro+ run on Tradecopia's infrastructure and are not affected by your local machine's conditions |
Trading style | Heavy scalping and large position sizes on small targets amplify slippage across all accounts. This is a market reality that affects all execution environments — not a Tradecopia limitation |
Risk management exit | If your risk manager triggered before this trade closed, see the section below |
Fill price differences that fall into one or more of these categories are broker-side outcomes. Tradecopia cannot control or correct broker execution results once the order instruction has been sent.
If the exit was triggered by the risk manager
If the risk manager triggered and your follower account closed at a price beyond your configured threshold, the risk manager functioned correctly.
When the risk manager fires, it sends a market close instruction to the broker. The broker executes the close at the best available market price at that moment — in volatile conditions or during a fast-moving exit, the actual fill may be beyond your threshold. This is a broker-side execution result, not a risk manager failure.
If the risk manager did not fire at all, see Why didn't my risk management settings trigger?.
If the discrepancy is still unexplained
If you have checked your broker order history and none of the factors above explain the fill difference, contact the Tradecopia support team with:
The affected account and broker
The instrument traded and approximate time of the trade
The actual fill prices from the broker order history on both the leader and follower
A description of what you observed
Significantly larger-than-expected discrepancies that cannot be explained by the factors above may indicate a transmission timing issue worth investigating.
