ADX dmPlus Inaccessible due to Protection Level

November 20th, 2010, 10:38 PM

I'm trying to add a simple condition to a NT7 indicator:

&& (ADX(13).dmPlus[0] >= ADX(13).dmMinus[0])

I get the error "Ninjatrader Indicator ADX.dmPlus is inaccessible due to protection level" & the same for dmMinus.

I'm just getting started with code, so you'll have to dumb down your answers for me please.

Try

DM(13).DiPlus[0]

DM(13).DiMinus[0]

It compiled. Tomorrow I'll see if the concept is any good.

OK, My logic was flawed.

Instead, I just want to modify the stock NT7 DM indicator to add a plot/alert when +DI and -DI cross.

Using my original logic, it will plot on every bar where the conditions are true. Do I need to use "CrossAbove"/"CrossBelow" instead... or is there is proper way to have the alert/plot occur only once when the condition becomes true and not again as long as the condition remains true?
Also, I want a dot to remain once it paints, even if COBC is set to false. Meaning if the lines cross and then uncross before close, the dot will remain. In theory, it could be possible for both buy and sell dots to plot on the same bar as long as other filters aren't added.

Here's what I have & it accomplishes what I want on the first cross, with the exception that it plots EVERY bar thereafter:

Code

if ((Close[0] > Open[0])
                && (DM(period).DiPlus[0] > DM(period).DiMinus[0]))

                {
                DrawDot(CurrentBar.ToString() + "dotbuy", true, 0, Low[0] - 5 * TickSize, Color.DarkGreen);
                 Alert("BuyAlert", NinjaTrader.Cbi.Priority.High, "PossibleBuy", "chime_up.wav", 15, Color.Black, Color.Green);
                }
                
            if     ((Close[0] < Open[0])
                && (DM(period).DiPlus[0] < DM(period).DiMinus[0]))
                
                {
                DrawDot(CurrentBar.ToString() + "dotsell", true, 0, High[0] + 5 * TickSize, Color.DarkRed);
                 Alert("SellAlert", NinjaTrader.Cbi.Priority.High, "PossibleSell", "chime_down.wav", 15, Color.Black, Color.Red);
                }

Remember, if you paint a dot that remains after the condition changes it will disappear if you refresh the chart.

Correct, that's why I use market replay to populate the chart rather than just refreshing it. I do that if any of my indicators are set to COBC=false. Using market replay to populate historical charts is the only way to see how indicators really behave.
Thanks.

OK, I finally got the syntax right for CrossAbove so the indicator is working as expected now.
