Volumes on Main Chart Most of these indicators require the Volume on Main Chart indicator wherein it acts like the global control centre (indi ON & OFF). Sorry, that is what it is, designed to work with each other. Like for example TZD indicator... the Volume on Main Chart triggers the update process once the volatility spikes up based on the last average pip count (e.g. from three previous bars - set TF or example 1-minute candle). And this besides from the normal trigger of set time in minutes or on a new bar. If v2v system/indicators don't seem to work on your end or found it useless, simply move on as there are literally thousands of other systems/indicators out there . . . and this may not be ready for you or is not for you! On how to use the system effectively will depend on your own utmost keen observation (or greater experience), due diligence, understanding, and prerogative. Hence, this may not be recommended for noobs... especially when using the VWAP & TZD indica...
