I would like to make sure that I can download tick, bid and ask info so from NT's servers so that I can test ideally a year of data.
I'd like some guidance as to what symbols NT Support recommends to use please. Ideally I would use a LONG and a SHORT ETF - (like SPXL and SPXS) but NT doesn't carry those.
Please advise which 2 symbols I should use.
Thanks
