Volume Monitor calculates the daily volume in the quote currency and displays a warning sign when that volume is below or above user-defined low and high limits.
For those not familiar with the term, quote currency refers to the second part of a trading pair such as EUR/USD or BNB/BTC.
One use for the indicator is for cryptos, where one who does not wish to trade low volume markets can rely on the indicator to flag them. The default values of 300 and 1000 for the low and high limits mean that when looking at XXXBTC charts, a yellow dot will appear on the chart when the daily volume of the market is lower than 300 BTC, and a green dot will appear when it is higher than 1000 BTC.
If your chart settings are configured to show indicator values, the first value shown by the indicator is the daily volume in the quote currency. It will be green or red, depending on the day’s price action. In order to show the value, an invisible plot must be printed on the chart and for it not to wreak havoc on the price, the indicator’s scale should be set to “No scale” (the default) or to a different one than the price’s scale.
