If you subscribe to the paid version of TradingView you get additional features such as the seconds chart and split chart features, but a paid subscription to TradingView is not required to use Market Cipher. Market Cipher will work fine with a free Tradingview account but you are limited to 3 indicators at a time.If you want to run all 4 Market Cipher indicators at the same time you will have to remove the volume indicator that is loaded by default.
