Volume Spike Indicator

Sorry I'm not following you, with key off I meant for your signal / alert the trend series offered is then where you want to work with closely, as it would directly offer you what's needed to setup the alert condition. The snippet I've shown could be entered for example in the OnBarUpdate() below the paint bar condition.

Thanks,so for the DownSwing i`d need to add the appropriate line?

Correct. Just the opposing condition then...

Ok,i did as you suggested,and now i get an alert on each and every tick

here`s the snippet:

{
if (Trend[0] == 1 && Trend[1] == -1)
Alert("myAlert1", NinjaTrader.Cbi.Priority.High, "up swing", "LB.wav", 10, Color.Black, Color.Yellow);
Alert("myAlert1", NinjaTrader.Cbi.Priority.High, "down swing", "LB.wav", 10, Color.Black, Color.Yellow);
if(CurrentBar == 0)
{
Trend.Set(Close[0] >= Open[0] ? 1 : -1);
Value.Set(Trend[0] == 1 ? Low[0] : High[0]);
return;
}

if (Trend[0] == 1 && Trend[1] == -1)
Alert("myAlert1", NinjaTrader.Cbi.Priority.High, "up swing", "LB.wav", 10, Color.Black, Color.Yellow);
Alert("myAlert1", NinjaTrader.Cbi.Priority.High, "down swing", "LB.wav", 10, Color.Black, Color.Yellow);

I would not expect that part to work, the second statement will be evaluated at each OnBarUpdate() call, you also did not add the proper opposing condition for the short swing in here?

Would try something like at the bottom of the OnBarUpdate(), below the paint bar code and outside of any other condition -

if (Trend[0] == 1 && Trend[1] == -1)
Alert("myAlert1", NinjaTrader.Cbi.Priority.High, "up swing", "Alert1.wav", 10, Color.Black, Color.Yellow);
else if (Trend[0] == -1 && Trend[1] == 1)
Alert("myAlert2", NinjaTrader.Cbi.Priority.High, "dn swing", "Alert1.wa", 10, Color.Black, Color.Yellow);

No,same result.

On which CalculateOnBarClose setting do you run this?

Thanks, that would explain it - then I would suggest including a check to FirstTickOfBar in your Alert conditions.

if (Trend[0] == 1 && Trend[1] == -1 && FirstTickOfBar)
Alert("myAlert1", NinjaTrader.Cbi.Priority.High, "up swing", "Alert1.wav", 10, Color.Black, Color.Yellow);
else if (Trend[0] == -1 && Trend[1] == 1 && FirstTickOfBar)
Alert("myAlert2", NinjaTrader.Cbi.Priority.High, "dn swing", "Alert1.wav", 10, Color.Black, Color.Yellow);

It seems to be working this way.Thank you for your assistance!

Excuse me,
when copying this snippet, I get the error "Trend doesn't exist in this context".
Why ?

...because you took it out of context here, the full indicator should be in post 12 of this thread.
