Thank you for the reply. I've been monitoring the HSI future for a month through live quote, and realize the high volatility in this market. Thank you for the warning.
Through some demo accounts, I've also seen that some futures company using the live last trade price, then they substract their SELL price by 10 and add their BUY price by 10. hence they have 20 points spread. Another, using the live bid price as their sell price and add 10 points for their buy price.
Through that observation, I want to know hows the IB quote their bid/ask price, so I can calculate their BEP .
cheers
