This is definitely the right decision. For some reason, newcomers hope that they will set up automatic trading, and money will pour on them from the sky.
And I think that this is a rather profitable solution that can help a trader who is just starting to work in the market. Just remember your first trading sessions, it was so difficult and so ambiguous. And here you always have something that allows you to orientate yourself in the market. And in the end, you do not have to just use ready signals and not think about them. You can use it as a kind of benchmark, which will help you find the most profitable positions that will allow you to earn here and now. So try, most importantly, to define strategies, so that you can get used to the market, and do not risk large sums, it is not a good solution...
Knowing human nature for what it is... IMO if those MQL scripts would have fulfilled developers goals then none would be publically available... As a kid i downloaded long list of free and paid metatrader EAs, tested alot. Only "good" ones were the ones that took advantage of simulating environment. Luckily i was unable to put those to "work" under live account due to age restrictions. At best you may find someone who is in the process of working capital up providing algotrading signals for subscription fee. Not to say its impossible to use MT&MQL or short scripts in general succesfully but IMO working software probably costs millions and is far beyond in complexity. I have MQL scripts for MT4/5 , but those only handle COM. I think my first post in this forum was about how to make that work best. Even that goal was hitting MQL4 limitations quite hard. Now years have passed , maybe MQL5 is capable of more idk. Start development&testing yourself. Dont rely on others for gathering info in this field. You may read 1000 forum topics and gain only few sentences of useful info.
