You can choose to "insert" the volume in MT4. This is an indicator of turnover. The greater the turnover, the higher the turnover rate. Because the foreign exchange market is too big, the hourly or even daily turnover and turnover rate are insignificant for a huge national currency, just like the turnover rate of 0.00 1% and the turnover rate of 0.002%. Although their turnover rate has doubled, it is completely ignored and there is no need to consider it for a huge currency. The above is just a personal understanding and is for reference only.
