One Candle Trend Strategy

Overview

OneCandleTrendStrategy is a simple trend strategy that makes decisions based on the analysis of a single candle.

Main Components

public class OneCandleTrendStrategy : Strategy
{
	private readonly StrategyParam<DataType> _candleType;
}

Strategy Parameters

The strategy allows customizing the following parameters:

• CandleType - candle type to work with (default 5-minute)

Strategy Initialization

In the OnStarted method, candle subscription is created and visualization is prepared:

protected override void OnStarted(DateTimeOffset time)
{
	base.OnStarted(time);

	// Create subscription
	var subscription = SubscribeCandles(CandleType);
	
	subscription
		.Bind(ProcessCandle)
		.Start();

	// Set up visualization on the chart
	var area = CreateChartArea();
	if (area != null)
	{
		DrawCandles(area, subscription);
		DrawOwnTrades(area);
	}
}

Processing Candles

The ProcessCandle method is called for each completed candle and implements the trading logic:

private void ProcessCandle(ICandleMessage candle)
{
	// Check if the candle is finished
	if (candle.State != CandleStates.Finished)
		return;

	// Check if the strategy is ready for trading
	if (!IsFormedAndOnlineAndAllowTrading())
		return;

	// Trend strategy: buy on bullish candle, sell on bearish candle
	if (candle.OpenPrice < candle.ClosePrice && Position <= 0)
	{
		// Bullish candle - buy
		BuyMarket(Volume + Math.Abs(Position));
	}
	else if (candle.OpenPrice > candle.ClosePrice && Position >= 0)
	{
		// Bearish candle - sell
		SellMarket(Volume + Math.Abs(Position));
	}
}

Trading Logic

• Buy signal: bullish candle (close price above open price) when there is no long position
• Sell signal: bearish candle (close price below open price) when there is no short position
• Position volume increases by the current position amount with each new trade

Features

• The strategy automatically determines instruments to work with via the GetWorkingSecurities() method
• The strategy only works with completed candles
• The strategy uses market orders for position entry
• The strategy applies a simple trend detection logic based on a single candle
• Candles and trades are visualized on the chart when a graphic area is available
