Я подписываюсь на события ticker на wss://api.poloniex.com. Сервер не мой, мне просто нужно собирать информацию из него, но у меня проблема с форматом.
У меня есть это событие и не могу найти правильный тип для такого сложного случая:
RX message: event [543453838537363, 3807360795988603, {}, ["BTC_BCH", "0.18447297", "0.18447297", "0.18410001", "0.06427077", "14359.75209355", "89775.00285182", 0, "0.19500000", "0.14000001"]]
Может кто-нибудь мне помочь?
