Oh I promised to report back (week ago) on how the IB cash account balance affects rapid intraday trading. Well Cutz and Tech/a are 100% right, as long as you maintain USD$25K account balance you can trade all day long (I had a few days with more than 10 trades) turning over the full account balance several times over. I don't know why IB help desk didn't tell me about this rule when I inquired (suppose I should have read the trading Ts & Cs more thoroughly), now I'm using IB for all my smaller trades.Actually did a quick search, Pattern Day Traders with small accounts may get flagged, please refer to this linked article, may be of help. https://ibkr.info/article/193
I want to do some more development using the IB API, anyone know of a good source of sample apps, tutorials and code (IB only have a few on their site)
