Unfortunately Valutrades cannot advise clients on how to develop indicators, expert advisors (EA’s) and Signals.
We can however suggest that if you go to visit: mql5.com this is the official site of Metaquotes the builder of the popular MT4 and MT5 trading platforms.
You will then need to register through the site to sell EAs, Signals and Indicators.
