Lookback regarding price (low) below cert level possible?

[MickeyHR]

I would prefer to use following kind of a condition as a checkup for a signal:

If the measured time series bar low has visited below a certain price level like SMA(5)-StDev(5) during 5 past days at any of those 5 days a signal occuring is valid.

Is defining this kind of an additional (strategic) condition possible with NinjaTrader?

Yes this sounds possible but complexity will depend on the type of chart being used. Are these daily bars or a smaller time frame?

does this mean you would like to look at the past 5 days and then if any one of them has a low that breaches the value you can take trades on the current day?

Hi,
Thank you so much for your fast response.

In my case daily bars.

Exactly like you state.

In that case you could do something like this

if(MIN(Low, 5)[1] < (SMA(5)[0]- StDev(5)[0]))

MIN(Low, 5)[1] //gets the minimum value of the lows over the past 5 bars starting 1 day ago

If each day has a different value you need to check over then you could solve this with a for loop

yourBool = false;
for(int i = 1; i <= 5; i++)
{
  if(Low[i]  < (SMA(5)[i]- StDev(5)[i]))
  {
     yourBool = true;
     i = 6;//to stop looping
   }
}

Looks perfect. Thank you so much.
