Would you confirm that is possible to have a refresh rate of 0.2 and incur no charges, please ? My understanding is that up to 20 requests can be made in one second. Am I right, please ?
Also, if mutliple markets are running triggers, how should the requests be calculated ?
e.g. if four markets are open, and refresh rate is 0.2, is the number of requests equal to 20 per second ?
