 Note that, if you're using the third format, simple arguments (float, bool, string... etc) will be used for calling the

+bbgo.Notify("%s found support price: %f", "BTCUSDT", 19000.0, kline)
+```
+
+The above call will render the first format string with the given float number 19000, and then attach the kline object as the attachment.
