tickerStream method
24hr rolling window ticker statistics for a single symbol.
These are NOT the statistics of the UTC day, but a 24hr rolling window for the previous 24hrs.
Implementation
Stream<WsTicker> tickerStream({required String symbol}) {
final channel = subscribe('${symbol.toLowerCase()}@ticker');
return channel.stream
.map<Map>(toMap)
.map<WsTicker>((e) => WsTicker.fromMap(e));
}
