Range Logic

[kenb2004]

I have a strategy that uses code that says
if (macd(Fast, Slow, Smooth)[0] > 50
|| (macd(Fast, Slow, Smooth)[1] > 50
|| (macd(Fast, Slow, Smooth)[2] > 50
|| (macd(Fast, Slow, Smooth)[3] > 50
|| (macd(Fast, Slow, Smooth)[4] > 50
|| (macd(Fast, Slow, Smooth)[5] > 50
&& Sell signal [0] goes here...)

Can you tell me how to do this as a range from current bar to 5 bars ago in one line of code instead of 6?

Thanks

Hello Kenb2004,

One option here is using CountIf()


if (CountIf(delegate {return MACD(Fast, Slow, Smooth)[0] > 50;}, 6) >= 1)
//Do Something

Says:
Look for this condition over the last 6 bars. If occurred more than once do something.

[kenb2004]

So you could use this for "at least" once?

if (CountIf(delegate {return MACD(Fast, Slow, Smooth3)[0] > 50;}, 6) >= 1)
//Do Something

[NinjaTrader_RyanM1]

Correct: >= 1 is more appropriate for your code snippet.

3 was placed there inadvertently and has been fixed. Thanks for letting me know.

Thanks, one other thing unrelated. How do I make this 50 line 'dashed' ?
Add(new Line(new Pen(Color.Blue, 2), 50, "50 line"));
thanks

[NinjaTrader_RyanM1]

You could do something like:
Lines[0].Pen.DashStyle = DashStyle.Dash;

[kenb2004]

Thanks, that works great.

If you wanted a condition to be true when it was true consecutively for 10 or more bars would this be the correct way to do this or is there a better way?

if (CountIf(delegate {return MACD(Fast, Slow, Smooth)[0] > 50;}, 10) >= 10)
//Do Something

Hi Ken,

Yes, using CountIf() like this will work as a consecutive function. The alternative to this is custom coding your own method.

There are built in functions for consecutive up and down closes:

I tried this and only got a yellow background color. Can you tell me how to get all 3 colors working? Logic I am attempting is when the EMA7 has been over the SMA20 for at least 10 consecutive bars, make background color green. When the EMA7 has been under the SMA20 for at least 10 consecutive bars, make background color red. If Not either of these make background color Yellow.

if (CountIf(delegate {return EMA(7)[0] > SMA(20)[0];}, 10) >= 10)
{
BackColor = Color.FromArgb(100,130,255,130); // Green Background Color, UpTrend
}
if (CountIf(delegate {return EMA(7)[0] < SMA(20)[0];}, 10) >= 10)
{
BackColor = Color.FromArgb(100,255,165,165); // Red Background Color, DownTrend
}
if (CountIf(delegate {return EMA(7)[0] > SMA(20)[0];}, 10) < 10
|| CountIf(delegate {return EMA(7)[0] < SMA(20)[0];}, 10) < 10)
{
BackColor = Color.FromArgb(100,255,255,150); // Yellow Background Color, Neutral
}

Ken,

To debug this, you'll want to focus on one statement at a time and use Print statements to keep track of the countif value.

Print(CountIf(delegate {return EMA(7)[0] > SMA(20)[0];}, 10));

In the code below I would like to enter a long position at 10 ticks below the closing price of the "crossover" bar. What should I replace "[0]" with? Since the crossover bar could be 1 of 5 past bars. Thanks
if (CountIf(delegate {return CrossAbove(WMA(Fast), WMA(Slow), 1);}, 5) >= 1)

EnterLongLimit(DefaultQuantity, Close[0] + -10 * TickSize, "Crossover Buy");

Hello Kenb2004,

You can work with Most Recent Occurrence. It returns the number of bars ago that the test condition evaluated to true within the specified look back period expressed in bars.

[kenb2004]

This appears to be what I need but I'm not sure how to apply it. Do you have any samples or examples of how to apply this method. In my strategy would I use it with CountIf() or instead of?

[NinjaTrader_RyanM1]

Here is an example that returns the number of bars ago for the most recent occurrence of Close[0] > Open[0]. The lookback period is 10 bars.

This is used instead of CountIf to return a different type of value.

int barsAgo = MRO(delegate {return Close[0] > Open[0];}, 1, 10);
if (barsAgo > -1)
Print("The bar high was " + High[barsAgo]);
