How to call the ATR of the selected cycle-hour K line?

Author: The Ninja, Created: 2016-02-03 17:16:00, Updated:

exchange.IO("api", “kline”, “symbol=btc_cny&type=1day&size=200”);

It's like I'm using IO and I don't know how to do it.

Zero exchange.GetRecords(PERIOD_D1);

ZeroThis IO function calls a function of the transaction class, which is not used by the K-line field class.

The NinjaHi, sorry, thanks for the reply, but I want to take 4 hours of K line, but I can't, exchange.IO (("api", "kline", "symbol=btc_cny&type=4hour&size=200"); will it still work? https://dn-filebox.qbox.me/2653ce6f564700ae5bf5087a3090bb7c4a50d32c.jpg
