i was looking at Binance API.

it seems there's not "classic" Ticker Call.
I mean 1 single api call that allows you to have LAST/HIGH/LOW/VOLUME.

Considering this page as the unique api available page : https://www.binance.com/restapipub.html

I only have this choise :

 /api/v1/ticker/allPrices

I only get all last price for all the markets. Not useful.

/api/v1/ticker/allBookTickers

I Only get best current prices. Not useful.

/api/v1/ticker/24hr

This is what i need, but it works only for 1 single market. So 1 API Call = 1 Ticker.

Binance have currently 152 markets.
So 1 Full Ticker Load is 152 API Call. That's a big big problem.
I never find an API System without the option of
- 1 Single API Call for Full Ticker Data
- A Parameter where i can concatenate all the Markets i need to get the ticker.

With current situation i don't think i'll be able to interface CAT without have a very big load of data/api call 
I'm not sure about what to do......results could be bad.....
