Read-onlyIdempotent

Scan the venue's listed instruments for ones matching conditions, instead of looking at the open chart. Rules combine price fields, any indicator plot, or a formula expression, with ALL/ANY matching. This is the tool for "which coins are doing X right now". It fetches history for every instrument in the universe, so it is slow and worth asking for once with the right conditions rather than repeatedly with narrower ones.
