I searched for signals that are compatible with my platform (metatrader 4), and I chose a FREE one to try out on my demo account I did everything according to the instructions to subscribe to this signal, but when I am entering my confirmation password of mql5, after clicking on subscribe, my "OK" button is not clickable I tried this for multiple different free signals, but all has this problem.
i think you are facing this problem for you demo account as In the client terminal's showcase, a real account can only subscribe to Signals from real accounts and a demo account can only subscribe to Signals from demo accounts.
