Relative volume (also known as RVOL) is perhaps the most important day trading filter in a trader’s toolkit. Relative volume tells traders how current trading volume is compared to past trading volume over a given period - More simply put, relative volume tells us how many shares have traded in relation to how many shares usually trade.

Volume is an incredibly important tool for active traders. Please enjoy our FREE Volume Data custom script (ThinkScript) for the ThinkOrSwim trading platform.
