How are you? I made a model to predict price trends in the next 1-2 seconds, can you ask if I'm using rest or websocket?

The Little DreamIn general, rest is used, ws is also used, this is designed specifically.

churchillxyGood. Thank you.

The Little DreamWhen.wait returns the result, it returns null, which means that the call failed and you can try again.

churchillxyIs there a compromise?

The Little Dream 不要对exchange.Go使用。

churchillxyHi, can you please use the Go function, can you use the _C error? Because I use the go function, sometimes I get an error like /upload/asset/246242c0deb75e739448c.png

churchillxyReceived, thank you.

The Little DreamIt is used to access, ```exchange.Go `` functionality.

churchillxyIf I use rest, can I read both the getdepth and getticker functions at the same time? I understand it is because of the two functions, so in the program, when running the two functions, the timing is different. Thank you.

The Little DreamI'm not being polite.

churchillxyGood, thank you.

The Little DreamYes, the Close property of the unfinished BAR is the same as the Last property value that GetTicker returns for the data (not counting the delay).

churchillxyPlease ask getrecords is the latest transaction price when the cycle is less than 1 minute?
