ATR based Stop Loss

[moon_rainz]

I am trying to have a ATR based stop loss. For example, if I entered a long EURUSD position at 1.5600 at close of bar, and ATR(14) at close of bar is 0.0020, my static stop loss will be 1.5600 - 0.0020 = 1.5580.

Under Initialize(), I included the following:

SetStopLoss("", CalculationMode.Ticks, ATR(14)[0], false);

However, when I tried to run the strategy, the log says:

"Failed to call method "Initialize for strategy 'SimpleMACross': ATR[barsAgo]: barsAgo out of valid range 0 through -2, was 0.

I would appreciate any advice.

a) please make sure there is historical data available for the instrument you backtest by e.g. pulling up a chart while connected.
b) try moving your SetStopLoss statement to the OnBarUpdate method

Hi Dierk,

Thanks. Your statement (b) works.

Here's my sample for readers facing the same problem:

if (CrossAbove(EMA(14), EMA(24), 1))
{
EnterLong(1, "");
SetStopLoss("", CalculationMode.Price, Close[0]-ATR(14)[0], false);
}
