Subject: Incorrect Unrealized P/L During Live Trading (Teton Order Routing)

Hello Sierra Chart Support,

I would like to report an issue that I have been troubleshooting. Below is the sequence of events exactly as they occurred.

1. Initial Observation

While trading live through Teton Order Routing to my IronBeam account, I noticed that the unrealized P/L displayed in Sierra Chart was incorrect. Although my trades were moving in my favor, Sierra Chart showed that I was losing money while the positions were still open.

2. Second Observation

Shortly afterward, I noticed that the prices displayed on my Sierra Chart no longer matched the actual market prices.

To verify this, I compared Sierra Chart with my TradingView chart displaying the same market. At one point, TradingView showed a bullish candle while Sierra Chart showed a bearish candle for the same time period.

Because of this, I suspected that Replay Mode might somehow still be affecting the chart. I am not saying Replay Mode caused the problem; this was simply the reason I began investigating it.

3. Troubleshooting Performed

• Verified Replay Mode was completely disabled.
• Created a new Chartbook to determine whether the original Chartbook had become corrupted.

The new Chartbook resolved the incorrect chart pricing. The chart now displays the correct market prices.

However, the unrealized P/L problem remained.

4. Verification of the P/L Issue

To verify the issue, I placed approximately five to six live trades through Sierra Chart using Teton Order Routing to my IronBeam account.

For every trade:

• The market moved in my favor.
• Sierra Chart displayed an incorrect unrealized P/L, often indicating that I was losing money.
• While the trade was still open, I compared the unrealized P/L shown in Sierra Chart with my IronBeam trading platform.
• The unrealized P/L displayed in Sierra Chart did not match what I observed in my broker's platform.
• As soon as I closed the trade, Sierra Chart immediately recalculated the trade and displayed the correct realized profit/loss.

This same behavior occurred on every test trade.

5. Final Troubleshooting Step

I then reinstalled Sierra Chart.

After reinstalling:

• The chart pricing issue remained resolved.
• The unrealized P/L issue still persists.

Today I reproduced the problem again. Once again, the unrealized P/L displayed by Sierra Chart was incorrect while the trade was open. I verified the position against my IronBeam platform during the live trade, and the unrealized P/L shown in Sierra Chart did not match what I observed there. As soon as I closed the position, Sierra Chart immediately corrected itself and displayed the proper realized profit/loss.

I also contacted IronBeam Support regarding this issue. After discussing the behavior and verifying that my orders are being routed through Teton Order Routing, they recommended that I contact Sierra Chart for further investigation.

Could you please advise what logs, settings, or diagnostic information you would like me to provide? I would be happy to perform additional testing if it will help identify the cause.

Thank you for your assistance.
