Each plan has limits, such as how many bots can run live and how many coins they can follow. The plans page lists them all.
When you reach one, Tradenos tells you which limit it is and what the next plan would allow. Bots above the limit wait on Track only.
Stop losses, exits and open trades are never interrupted by a plan limit. That also holds when you move to a smaller plan or a trial ends.
These things have no limit on any plan: the money in your bots, saved strategies, charts, indicators and manual trading.
