What's wrong with the profit exactly?
For a live TS position?

If the broker provides a price basis for the position, then the correct profit can be shown.

See the two attached photos. One from WL and one from TS. Specifically, MCLZ24.

Yes, this would be for a trade executed on TS

Thanks. We'll look in to that.
It seems that the SymbolInfo (Point Value) wasn't applied.

After looking into it, a futures position requires a record (for the time being) in Markets & Symbols to get the multiplier. We can work on that when that information is already available from the broker.

For now, you'll need to enter this record in Tools > Markets & Symbols > Symbols. It may required a WL restart to take effect if you've already opened the Accounts tool.
