getTradeStatistics method

Future<List<TradeStatistics3>?> getTradeStatistics()

Retrieves trade statistics from the Haveno gRPC server.

This method sends a GetTradeStatisticsRequest to the Haveno server and expects a GetTradeStatisticsReply in response, containing a list of TradeStatistics3. If the client is not connected to the gRPC server, a DaemonNotConnectedException is thrown.

Example:

try {
  final tradeStats = await tradeClient.getTradeStatistics();
  if (tradeStats != null) {
    for (final stat in tradeStats) {
      print('Total Trades: ${stat.totalTrades}');
    }
  }
} catch (e) {
  print('Error fetching trade statistics: $e');
}

Returns:

• A Future that resolves to a List<TradeStatistics3>? containing the trade statistics, or an empty list [] if no statistics are found or an error occurs.

Throws:

• DaemonNotConnectedException if the Haveno client is not connected to the server.
• Catches GrpcError to handle any gRPC-specific errors.

Implementation

Future<List<TradeStatistics3>?> getTradeStatistics() async {
  // Ensure the Haveno client is connected.
  if (!havenoChannel.isConnected) {
    throw DaemonNotConnectedException();
  }

  try {
    // Get the trade statistics client from Haveno.
    GetTradeStatisticsClient? tradeStatisticsClient =
        havenoChannel.tradeStatisticsClient;

    // Request trade statistics from the server.
    GetTradeStatisticsReply? tradeStatisticsReply =
        await tradeStatisticsClient
            ?.getTradeStatistics(GetTradeStatisticsRequest());

    // Return the list of trade statistics from the response.
    return tradeStatisticsReply!.tradeStatistics;
  } on GrpcError catch (e) {
    // Handle gRPC errors using the GrpcErrorHandler mixin.
    handleGrpcError(e);
  }

  // Return an empty list if an error occurs.
  return [];
