It would be helpful to see your Positions tab.

It looks like a trade on bad data. LIke Glitch said.. check Positions - sort for the highest Profit and Profit % (they can be different trades).

Is there a possibility to delete the cache and fetch again all data from Norgate?

You're confirming a data problem?
Are you sure the data for that trade (or trades) was from Norgate and not from another provider in the list?

Re: Norgate - Norgate data "cache" is a local database. Report problems to Norgate for corrections.

I still have this problem.
It happens at 27. February 2025:
Is there a way to delete the complete Norgate and WealthLab Cache?

I think it comes from Norgate data: I'm reinstalling now the databases:
- US Equities
- US Equities Delisted

It didn't worked. I still have this bad issue.

You should probably ask on the Norgate web site, they develop the extension.

Unfortunately its again broken.
And the support of Norgate is not answering.
I think Norgate is dead.

This issues happens only with Norgate data.

The problem data/symbol should be very easy to isolate. See Post #2. Just find the trade or trades that's doing it.

It could be that the SymbolInfo in your MarketManager is misconfigured.

Ok I found out something:
The problems appears only if "Collect dividends on backtest position" is enabled.
The position tab has no view when I will receive dividends, but I guess one dividend number is wrong.
The profits in % seems to be ok.

Indeed, can you let us know what Event Providers you have enabled in the Data Manager?

Also open a chart for NVDA and position your mouse over the "D" dividend in March 2025. Let's see if we can identify which Provider issued the wrong data. I just went through all the dividend Providers for NVDA and none of them are issuing bad data at my end so it might have been a temporary glitch that we need to clear.

Nasdaq was enabled. I disabled it, now it works. I no more see the bugs.

The Nasdaq Events don't explain it - Nasdaq Dividends are a good source and are correct for me, and you didn't show they were wrong, which is what Glitch was asking for.

The problem is that that position size is out-of-whack. The profit for the size is correct. For some of those out-of-whack trades, the size is like $100M, but the other sizes are more like $7K. Events do not explain that. Something else is seriously wrong with your code or setup.

@Cone: I did not found the wrong source value in the chart. If I see it, I will post it here.
