dependencies:
  kline_aggregator: ^0.0.1

Usage

Here's a simple example of how to use the package:

import 'package:kline_aggregator/kline_aggregator.dart';

void main() {
  // Create a list of trades
  final trades = [
    Trade(
      timestamp: DateTime.now(),
      price: 100.0,
      amount: 1.0,
    ),
    // Add more trades...
  ];

  // Aggregate trades into 1-minute K-lines
  final klines = aggregateToKlines(trades, Duration(minutes: 1));

  // Use the K-line data for charting or analysis
  for (var kline in klines) {
    print('Time: ${kline.openTime}');
    print('Open: ${kline.open}');
    print('High: ${kline.high}');
    print('Low: ${kline.low}');
    print('Close: ${kline.close}');
    print('Volume: ${kline.volume}');
  }
}
