Implementation

void getOpenInterestPeriodic(
    {required String symbol,
    required String interval,
    int? limit,
    required Duration period}) {
  log.d('ByBitRest.getOpenInterestPeriodic');
  streamGroup!.add(Stream.periodic(period, (_) {
    return getOpenInterest(symbol: symbol, interval: interval, limit: limit);
  }).asyncMap((event) async => await event));
}
