In modern/better data feeds volume data is split into up and down volume. That is, volume transacted at the ask or the bid. This gives a more accurate picture of buying versus selling volume. The Better Momentum indicator uses this up/down volume, when it is available, by default. However, from time to time and in some markets the data is unreliable. If you want to turn off the use of this up/down volume, simply set the “UseUpTicks” input to false. When the input is set to false or when the up/down volume data is not available the Better Momentum indicator uses the OHLC price data to calculate proxies for buying and selling volume.
