Description

As a big fan of both cTrader and TradingView, I developed a plugin to embed TradingView charts directly inside cTrader. It allows me to analyze graphs in TradingView but trade in cTrader.
Advantages:
Add as many TradingView charts as you want.
Place a TradingView chart next to a cTrader chart to compare.
Disadvantages:
TradingView charts are not persisted, so all chart data is lost when you close cTrader.
TradingView prices may differ from your broker's prices, so double-check the actual price in cTrader before trading.
How to use the plugin:
Download the plugin
Double click on the downloaded file to install it
Find new “TV” icon in the top menu
