VC and CMC are the stocks that are off. Does someone has an idea?

I think this difference can be caused when MultiCharts calculates the open P/L for one of these screens while retrieving the open P/L from the broker for the other screen. (That's my idea at least; I cannot find a source for that.)

If that's the case, then the wildly different results are probably due to incorrect QuoteManager settings. Particularly the big point value might be worth checking.

Siscop,

The difference comes from different calculation methods used.
In Portfolio Real-time Auto Trading Open P/L is calculated based on the chart prices, i.e on last Close. While calculation of Open P/L in Order is Position tracker depends on the option selected in Broker Profiles -> Interactive Brokers -> Unrealized Profit Calculation Mode.
