What are reasons when ChartTrader doesn't obtain the executed order's position

[ttodua]

Most time, when strategy is running in live, ChartTrader obtains the positions correctly.
However, once in a while there is occurence, when the strategy opens a position (i.e. reverse or from flat) but the ChartTrader doesn't show positions.
Here is another example. It closed existing position and opened short position. However, CT didnt see this.

What are the typical reasons which might explain such occasions?
this has been happening in live. such things occur once in a while. In most cases, the trades are well synced by CT, but as above example (and sometimes) it has problems.

Hello ttodua,

Thank you for your post.

Can you confirm this order was submitted while the strategy was running in real time? I note it looks as though the strategy is not currently active at the time of the screenshot -- I'm not seeing the lines that usually connect strategy orders, and I note the chart has been scrolled back from the current bar.

Thanks in advance; I look forward to assisting you further.

Is not on screenshot visible, there is green line, which connects to the "Close" arrow. and yes, i confirm, it was realtime. So, how one might note that strategy was not active? unfortunately I cant say 100% sure if strategy was active or not by the time of screenshot
So, you might suspect some possible error which causes strategy to shut down? but i am sure it was working and was not shut down.

for everything that happened during 12:30 and 12:55:
here trace : [redacted]
here log : [redacted]

my doubts lean to the fact, that in logs there is not "close position" one, which should be generally when strategy reverses position...

Hello ttodua,

Thank you for your reply.

You've started the strategy with an existing position on the account. When the strategy started running, the first thing it did was calculate it should have had a position in the opposite direction of the existing position, which it submitted, leaving your strategy position out of sync with the account position and resulting in the odd lack of lines you saw.

We can see this from the log here:

This is occurring because you are using Wait Until Flat as your Start Behavior when there was an existing position on the acccount, which does not submit a synchronization order to sync your account position to the strategy position. I would suggest, if you have an existing position on an instrument, that you use Wait Until Flat, Synchronize Account instead.
