TradeStation paper accounts may reject take profit and stop loss orders if decimals are not rounded correctly. Traders should adjust their signals, and TradersPost is investigating a potential fix.

Why Does TradeStation Reject Some Take Profit and Stop Loss Orders?

Traders using TradeStation’s paper trading account have reported order rejections when submitting take profit and stop loss percentages. The issue occurs when price values are not rounded to the nearest decimal, causing TradeStation to reject the orders.

This problem appears to be specific to TradeStation’s paper trading environment and does not occur in live TradeStation accounts.

How to Fix This Issue

Modify the Signal to Round Values – Traders can adjust their signals to ensure price values are rounded to the nearest acceptable decimal before submission.

Check Formatting on the TradersPost Side – The TradersPost team is investigating whether the system can automatically round values before sending them to TradeStation.

While TradersPost already formats order values before submission, further review is being conducted to confirm why this issue occurs.

Conclusion

TradeStation’s paper trading account may reject take profit and stop loss orders if the price is not rounded correctly. Traders can modify their signals to ensure proper rounding, and the TradersPost team is reviewing potential formatting improvements to prevent rejections.
