In cTrader screen, please go to “Links” and select “cAlgo”.
You may need to install the cAlgo first if you haven’t.(cAlgo and cTrader are different softwares.)
cAlgo opens up and it looks similar in screen display to cTrader.
After opened cAlgo, you need to login to your account which is same as the cTrader account, then you will be able to build, modify the instances(programs).
Once you apply an instance to a symbol, a price chart opens.
