Having an issue with using Value[0] in ATM Strategy

[jamestrader21x]

I'm trying to use this line of code "Value[0] = SMA(BarsArray[1], 10)[0];"

For some reason, the strategy does not like this line of code. It won't enable the ATM Strategy. If I comment it out, it enables. What's the problem? Here if the first few lines of code:

protected override void OnBarUpdate()
{
if(CurrentBars[0] < BarsRequiredToTrade || CurrentBars[1] < BarsRequiredToTrade)
return;

Value[0] = SMA(BarsArray[1], 10)[0];

double BarMADiff = Math.Abs(TSI(BarsArray[1],10, 34)[0] - EMA(TSI(BarsArray[1],10, 34), 4)[0]);

// HELP DOCUMENTATION REFERENCE: Please see the Help Guide section "Using ATM Strategies" under NinjaScript--> Educational Resources--> http://ninjatrader.com/support/helpG...strategies.htm
// Make sure this strategy does not execute against historical data
if(State == State.Historical)
return;

if (PositionAccount.MarketPosition == MarketPosition.Long || PositionAccount.MarketPosition == MarketPosition.Short)
{
CloseStrategy(atm_id);
}

I think I know what my problem is. That line of code Value[0] = SMA(BarsArray[1], 10)[0]; is part of an MA indicator. I'm not referencing it in the strategy.

No. That's not the problem.

Hi James, thanks for posting.

First, check the Log tab of the Control Center for any errors coming from the script. If you are getting a BarsAgo error, there are not enough bars on the chart to process the command. This simple test script works for me:

State.Configure:
AddDataSeries(BarsPeriodType.Minute, 5);

OnBarUpdate:
if(CurrentBars[0] < 10 || CurrentBars[1] < 10) return;

Print(SMA(BarsArray[1], 10)[0]);

Kind regards,

I'm using IsRising and IsFalling in my ATM Strat. Instead of using Value[0], I just passed in the SMA in to the methods. IsRising(SMA(BarsArray[1], 10))... It's working.
