I' m new to IG and am a bit confused about how tradings fees are calculated. Am I right in understanding that one has to pay the standard trading fee in the first month no matter what, and from the second month on, it's zero trading fee if one keeps trading 3+ US stocks per month forever? But what if I don't trade in the second month, is the trading fee zero for month two and standard trading fee for month three? Many thanks! Month one: 3 US stock trades - trading fee 3 x $10 Month two: no trading fee, regardless of number of trades in month two? Month three: standard fee if 0-2 trades in month two, and zero fee if 3+ trades in month two?
