I try to find some apps for indicators. To alert me when indicators for some coin reach some value but I could not find any apps for that so I am trying to create one.

I just start working on it there are tons of stuff that needs to be added so every suggestion is welcome.

For now, I just add RSI and MACD signals(that are the main signals that I am using for trading) and maybe MACD can be updated to work in multiple ways. If anyone has some suggestions I am open

I am thinking to add a third signal but not sure which one. Thinking about Bollinger bands.

So what do you think?
