Al ya hear about is SPY and QQQ... but I have done the homework and IWM actually has better stats for short term trading. SPY/QQ daily range is .90% / 1.62% but IWM is 1.76% if you play gaps,,, SPY average Gap .42% IWM .70% so, why do you never hear much about trading IWM?
Because it's small, and size matters in this world. SPX SPY DOW NASDAQ are all that matters. I use a Motorola phone, you rarely hear about these things. You only hear about Apple and Samsung. If you like day trading stock, consider day trading options instead. It's the same concept, but much more magnified DeseyJ
Day trading options on the SPX... you're on your way to becoming a rich man. The only tough magical part is knowing how to time it to ride that full wave movement...this is where many people falter and crack and fizzle out
