For example, ratio is 1:1, then it is considered Market Breadth is Neutral.
PS: Currently TradingView provides only NASDAQ Composite Market volume data. I have requested them to provide Primary NASDAQ volume data. If they respond with new ticket for primary NQ data, I will update the script and publish the updated version. So if you have got similar table on ToS, you would see minor difference in NQ ratio.
In true TradingView spirit, the author of this script has published it open-source, so traders can understand and verify it. Cheers to the author! You may use it for free, but reuse of this code in a publication is governed by House Rules. You can favorite it to use it on a chart.
