This I think is a worthy idea to explore further. I also ran into this thread last year and spend a few months working on it and spent a lot of hours. I had a script communicating with a Node.js script I wrote and MT4. I wasn’t able to reproduce good results. Sometimes it was good at predicting news but other times it gave false signals. It could also be the brokers I was using. I used data from 4 different brokers to compare.
I will follow your thread and provide any guidance and answer questions from time to time 
Good luck!
