Forex With Volume Related Studies
Unlike futures, with spot forex, volume information is not readily available due to the decentralized nature of that specific market. This is a function of what is available via the API and not a limit imposed by MotiveWave. In this case where historical volume is not provided, MotiveWave will assign a value of 1 to every tick. The total ticks for that period are added and presented as volume. MotiveWave will also tally the separate tick totals for bid and ask.
Although you can use tick volume, it still does not report the actual volume taking place so for this reason using tick volume can only be thought of as a proxy for real transaction volume.
