If you write indicators with a free account and you have more than 5 personal scripts saved, you are in the watchlist, or should I say blacklist of hackers. They can distort your indicator to generate numerous false signals or make your indicator to repaint more frequently, causing you to enter trades in the wrong direction.
Those pop ups and ads about subscription aren't there for nothing.
Initially they were editing my scripts after downloading uninstallable apps in my phone, but now they have a new way of doing that.
How they do this is by cloning your script and changing the algorithm as the master code.
After they do this you will notice a change in your signals, false signals will appear more frequently. The initial coding you did will never change the indicator back to how it was unless you edit the scripts and do the opposite.
For example if buySignal = rsi > 50 was your initial long condition, after they clone your script, if you change the operator from > to <, the indicator behaviour will change to how it was initially.
In other words, they are changing algorithms.
They may send you MMS messages, and when they hack your phone and didn't find your MT4 or MT5 live account, they will hack all your devices when you are asleep with your data on, just to get your live account and ruin it with bad trades. They will download uninstallable apps in your phone through your Google play store, such as android emulators and mirroring apps to see what you do with your phone so that they will know how to supervise your live trades.
