Indicator not behaving as expected

[CSharpTrader]

Hi all. I'm getting started with indicator scripting today. I've got a couple compiling/ running to generate alerts, but the one that is generating alerts is giving false signals. Hopefully, it's me. My indicator is simple... I want to return "1" to fire an alert from market analyzer. I'm looking to fire it when the latest period has the lowest low in 10 periods, and a high that it higher than the 2nd latest period, with 2x the volume of the 2nd latest period. I've attached two charts that show what it fired on (2nd latest candles shown on each). The charts are on 15 min bars, same as the column in market analyzer, and they show that all my criteria aren't met. Hopefully someone can help.. Here's my main method:

protected override void OnBarUpdate()
 {
     if ((Low[0] < Low[1]) && (High[0] > High[1]) && (Volume[0] >= Volume[1]*2) && (MIN(Low,10)[0]==Low[0]))
         Plot0.Set(1);
     else
         Plot0.Set(0);
}

Hello CSharpTrader,
If you apply the indicator on the chart and on the market analyzer then do the values match?

I look forward to assisting you further.

Not sure how...

I don't know how to do that.. if I'm not mistaken, my indicator has no graphic component... I thought I was just coding it to return 0 or 1 to be used in the alert.

Scratch that... I added it, I see that it does match. But at the time it fired, it was way off..

Hello CSharpTrader,
Glad you could make it work.

Unfortunately we cannot say anything for sure unless we could replicate it at our end. If you can replicate the scenario then please let us know the procedures on how to reproduce it and we will be happy to investigate it further.

I look forward to assisting you further.

If i can replicate it... it what sense? I can give you all the info you'd like to know. Let me ask you this... could it be getting calculated since the period bar it's firing on is getting grabbed within the lookback period? I thought lookback period had to be set to access past data properly for the script..

Hello CSharpTrader,
Look back period is relevant if your indicator references to historical data for calculating the values. Please refer to this thread which discusses it in more details
