A common issue that some users encounter on TradersPost’s paper trading platform is seeing unusually large position sizes when trading micros, particularly in futures. This problem is rooted in how the paper trading system processes data and fills orders.
One of the primary reasons for this issue is that the TradersPost paper broker doesn’t automatically have live market data for futures. When users place a limit order, the system instantly fills the position at the entered limit price, but it doesn’t accurately reflect current market conditions since it lacks a live quote. This can lead to discrepancies in position size and performance, with the platform sometimes showing a massive or distorted position.
To solve this, you need to connect a broker that provides futures market data, such as TradeStation. This connection allows the paper trading broker to fetch live quotes, resulting in more accurate position sizes and pricing. Without this data, the paper broker simply assumes a fill based on the limit price entered, which leads to inaccuracies in how positions and P&L are displayed.
When trading micros (such as Micro E-mini futures), which are smaller in size than regular futures contracts, the issue can become more apparent. Since micros are a fraction of the size of their standard contracts, the system may still display disproportionately large positions due to the lack of accurate data. TradersPost has acknowledged this issue and is working on long-term improvements to provide a more realistic paper trading experience.
The paper broker was initially developed for automated testing, but it became a feature for users who want to paper trade without a live broker connection. While it has been useful for testing strategies, the current system lacks certain features such as commissions, slippage models, and accurate order fills. The team is considering adding these enhancements in the future, which would improve the overall trading experience on the platform.
However, for now, users experiencing large or inaccurate positions with micros on paper trading can mitigate the issue by connecting a broker that provides live market data for futures.
