Definition

A collection of Trade objects. You can access a trade object by providing an index value. Trades are indexed sequentially meaning the oldest trade taken in a strategy will be at an index value of zero. The most recent trade taken will be at an index value of the total trades in the collection minus 1.

Methods and Properties

TradesCount	An int value representing the number of trades in the collection
EvenTrades	Gets a TradeCollection object of even trades
GetTrades()	Gets a TradeCollection object representing a specified position
LosingTrades	Gets a TradeCollection object of losing trades
TradesPerformance	Gets a TradesPerformance object
WinningTrades	Gets a TradeCollection object of winning trades

Examples

Example 1
protected override void OnBarUpdate() { // Accesses the first/last trade in the strategy (oldest trade is at index 0) // and prints out the profit as a percentage to the output window if (SystemPerformance.AllTrades.Count > 1) { Trade lastTrade = SystemPerformance.AllTrades[SystemPerformance.AllTrades.Count - 1]; Trade firstTrade = SystemPerformance.AllTrades[0]; Print("The last trade profit is " + lastTrade.ProfitPercent); Print("The first trade profit is " + firstTrade.ProfitPercent); } }

Example 1

protected override void OnBarUpdate()
{
// Accesses the first/last trade in the strategy (oldest trade is at index 0)
// and prints out the profit as a percentage to the output window
if (SystemPerformance.AllTrades.Count > 1)
{
Trade lastTrade = SystemPerformance.AllTrades[SystemPerformance.AllTrades.Count - 1];
Trade firstTrade = SystemPerformance.AllTrades[0];

Print("The last trade profit is " + lastTrade.ProfitPercent);
Print("The first trade profit is " + firstTrade.ProfitPercent);
}
}

Example 2
protected override void OnBarUpdate() { // Once the strategy has executed 20 trades loop through the losing trades // collection and print out the PnL on only long trades if (SystemPerformance.AllTrades.Count == 20) { Print("There are " + SystemPerformance.AllTrades.LosingTrades.Count + " losing trades."); foreach (Trade myTrade in SystemPerformance.AllTrades.LosingTrades) { if (myTrade.Entry.MarketPosition == MarketPosition.Long) Print(myTrade.ProfitCurrency); } } }

Example 2

protected override void OnBarUpdate()
{
// Once the strategy has executed 20 trades loop through the losing trades
// collection and print out the PnL on only long trades
if (SystemPerformance.AllTrades.Count == 20)
{
Print("There are " + SystemPerformance.AllTrades.LosingTrades.Count + " losing trades.");
foreach (Trade myTrade in SystemPerformance.AllTrades.LosingTrades)
{
if (myTrade.Entry.MarketPosition == MarketPosition.Long)
Print(myTrade.ProfitCurrency);
}
}
}
