Im still not opening due to my current device but BB and EMA lines is what commonly use of traders for their signal. This is a good addition to your app. How many indicator can you input on your ap that can work at the same time to give a signal?
I saw how it's working on the TradingView it's good but I can't create an alert with the multiple indicators or maybe I don't know how? Also, I could create the EMA but in what way? If the price hit EMA line to alert the users? Is that enough?
You can only set an alert on indicator that you are using on your actual chart. You cant see all the indicators on the alert except if its being use by you. Yes hitting the EMA line sufficient but if you can do an alert when EMA lines cross to each other then it will be better. Use only popular indicator for your indicator like Bollinger, MACD, RSI and EMA to make it simple.
Btw does the app will be available soon on for IOS or are you just prioritizing android for this app development? Kudos on your hard work. I will give a feedback once I use it this weekends after I get my fund for trading. This is the best for swing trades!
