Volume Profile indicators are calculated using the data for the same symbol from the lower timeframes. For example, to calculate the Volume Profile for one daily session, we load all 1m bars that were traded in that daily session, analyze the price levels where they were traded and the direction that the price moved in – if the bar closes above or equal to its open, this counts as an Up bar, otherwise it's a Down bar. Once analyzed, this data is added to the Volume Profile histogram.

The particular logic used to decide which lower timeframe should be used for the calculation differs on an indicator-by-indicator basis.

Volume uses in the calculations
Volume Profile uses the following types of volume:

trade volume - for stocks.
tick volume* - for indices/forex and crypto cfd
base or quote volume - for crypto
* tick volume indicates the amount of price updates.We use up/down volume instead of buy/sell volume and calculate VP based on a price direction inside bars: if close >= open, we take it as an Up Volume, if close < open, it's Down Volume.
