This is my first post, although I have been reading for a while.
By way of background, I am a competent Matlab user, and have spent the past few weeks analysing historical end-of-day data that I bought off eoddata. I have developed a strategy/algorithm that in leave-one-year-out backtesting produces some decent returns. My algorithm involves intraday trading in that it is based on buying (and/or shorting) stocks at the opening price, and selling (or exiting the short) at the closing price (as close to these prices as I can get).
My question is simply: Do you have any advice on which online broker to go with? I only want to do intraday trades. Ideally I would be able to trade across different exchanges (ASX, NYSE, NYME etc), and go long and short, but I will begin with just the ASX and the long-side.
I know it's a question that's been asked a million times, but I figure my specific conditions may impact the advice offered...
Another thing that may be of interest is that I will have 10-30k capital, and ideally be looking to take on up to 50 small intraday positions. I have yet to work out whether the fees involved in so many positions will kill my returns, because I'm not sure what the fees associated with such a trade typically amount to...
Thanks in advance for any advice - I think this forum is a really valuable resource!
