probleme with SMA 5 bars ago

[Pcomm69]

Hi,

in an Indicator in 70 Tick, I need SMA, 5 bars ago :

if ((SMA(50)[5] > SMA(100)[5])
&& (SMA(100)[5] > SMA(200)[5]))
{
PlaySound(@"C:\Program Files\NinjaTrader 7\sounds\Alert4.wav");
}
dont made sound Alert4

BUT this next works perfectly in 0 Bars ago and ma
if ((SMA(50)[0] > SMA(100)[0])
&& (SMA(100)[0] > SMA(200)[0]))
{
PlaySound(@"C:\Program Files\NinjaTrader 7\sounds\Alert4.wav");
}
give the Alert4 sound

Where is the difference ?
What can I do to use SMA (X) in 5 bars ago

Thanks in Help

Hello,

If you are not first checking how many bars are loaded before checking a barsago value you will get an error.

Try adding this above the statement you provided:

if(CurrentBar < 5) return;

This prevents the script from running until you have 5 bars loaded, then it can look back 5 bars.

Please let me know if I may be of additional assistance.
