Hi all,

I am thinking to build a website where users would be able to analyze signals of some crypto gurus. There are lots of channels where users can get signals, but I never found a summary that checked which of them actually works..

Users will be able to provide:
- Coin pair: NAV/BTC - Signal time: 20/03/2021 15:55
Result will be:
- Price at signal: 0.000045
- Price now: 0.0000055
- Diff: 20%
- All time high (what you could have potentionaly earned): 0.000090
- All time high / Price at signal: 50%
User defined columns:
- Price x minutes after the signal - user can choose the amount of minutes. For example, I would like to know the effect of the signal in the next 5 minutes
- Price x days after the signal

It will be in a form of a grid and users will be able to provide multiple signals. This way test a specific signal channel and see how many of the signals were correct and etc.
Users will be able to easily copy-paste into excel from the grid for further analysis Or copy from excel into the grid.

At the same time I am going to test myself all the most popular signal channels and keep an up-to-date list with analysis and ratings of the channels.
All this will be done via Binance API.

I am aware that users could potentially do that in Cryptosheets after setting it up correctly (which is not easy enough for most users), but i would like to build a web version and Cryptosheets has a limit of 1000 calls per month, so it won't work for something public.

I have two questions:
 
1. Does anyone know of something already existing that does something similar?
2. A question for users that follow these kind of channels: How do you check the signals currently? how do you know to which channel you should listen to?
