That really depends on the number. What's your daily average trade? TT Standard is $50/month while TT Pro is $400/mo and $4 round trip. Also AMP provides Co-location for $99/mo via CQG (https://offers.ampfutures.com/colocation-pricing-server-specs-request).
It depends on the day Could be as much as 30 trades But if the markets aren’t setting up may 2 or 3. TT standard would be ok. I don’t use a lot of platform techs. Just really basic. Bollinger bands and Stochastics.
