Object Reference Exception

[Space123]

I am relatively new to C#/NT - would someone be kind enough to explain to me why this code runs fine:

if (ioLEntryOrder != null && ioLEntryOrder.Token == execution.Order.Token)

ioLStopLoss = ExitLongStop(0, true, 100, ioLEntryOrder.AvgFillPrice - 2 * dEntryATR, "StopLoss", "LongEntry");


if (ioLEntryOrder != null && ioLEntryOrder.Token == execution.Order.Token)

ioLEntryOrder2 = EnterLongStop(0, true, 100, ioLEntryOrder.AvgFillPrice + .5 * dEntryATR, "Entry2");


but this code

if (ioLEntryOrder != null && ioLEntryOrder.Token == execution.Order.Token)
{
ioLStopLoss = ExitLongStop(0, true, 100, ioLEntryOrder.AvgFillPrice - 2 * dEntryATR, "StopLoss", "LongEntry");

ioLEntryOrder2 = EnterLongStop(0, true, 100, ioLEntryOrder.AvgFillPrice + .5 * dEntryATR, "Entry2");
}

generates "Error in calling the 'OnExecution' method for strategy "strat1": Object reference not set to an instance of an object. aren't these pieces of code really the same thing?

Hi Ben, yes it looks like the needed '!= null' check is included in both cases, you would need to add prints to check which part exactly throws you the error in your code.
