IBKR allows USD.CAD trade to 0.00005 decimal points. For example 0.00006 is not allowed. However, the detailed order book shows people requesting 0.00007 or 0.00003 for example and some of my trades get filled at those levels but I can not set to five decimal places other than 0.00005 difference. IBKR charges their fees separately for Forex trades and say they are proud to offer many decimal points but I am wondering if there is a better platform than them which provides full 5 decimal points or even 6 decimal points? Thanks,
