I recently joined IG, was trading with other broker for last few years.
I'm using custom indicators and expert, all stopped working when I transfered it to IG. Apparently MarketInfo(Symbol() return wrong or no value e.g.
MODE_SWAPLONG and MODE_SWAPSHORT return 0 on all currency pairs.
MODE_TICKVALUE return 0.1 on all pairs etc.
At this moment I just testing all functions to make sure that all my tools works correctly.
I don't know if this is relevant but account base currency is set to GBP
