Education only, not investment advice. The answer comes from the numbers you typed in, not from your account or the market. Simulated results are hypothetical and have limits: real trading has slippage, gaps, changing results and emotions. Trading leveraged products can lose money quickly, including all of it. Risk warning
Educational only, not financial advice; trading involves risk.
Relative volume divides a bar's volume by the average volume of the bars before it. At 1× the bar was as busy as usual; at 2× twice as busy. Traders use it to spot bars where something happened: a breakout on heavy volume is taken more seriously than one on light volume, and a quiet pullback is read differently from a heavy one. Volume is lopsided, with a few very busy bars, so the page also gives the ratio to the median and the bar's rank.
