I am going through my annual hair-pulling exercise with IB with regard to my FX trades and I just noticed in the CASH REPORT on the annualized calendar transaction summary, something called CASH FX TRANSACTION GAIN/LOSS. What is this? P/L foreign stock and futures trades reconverted back into dollars? It can't be my P/L from cash FX trades, as IB admits it does not summarize those. Thoughts?
