Looking for a great Sentiment indicator

 
Hi, I have started a project trying to make an expert advisor in mql5 that uses market sentiment to make it's trades, but I cant find a decent Sentiment indicator writtten in mql5. I was hoping someone here might be able to reccomend something good. Ideally I am looking for an indicator that bases it's sentiment calculation based on client data from real brokers, as opposed to being calculated through price action, something that does not repaint, and has indicator buffers that are easy to find.
