Rectangle on BB

[r3n3v]

When I try to draw a rectangle when price crosses above or below the BB It doesn't always work. Why is that?
I'm just using a simple cross above or below bollinger.upper or bollinger.lower.

Hello r3n3v,

Thanks for your post.

Can you show your code?

Can you clarify what you are trying to show/indicate with a rectangle?

Are you testing on live data, historical data, or Playback with market replay data?

What calculate setting are you running the script on?

Live Data. I've used both PriceChange as well as Tick.

if (CrossAbove(Bollinger1.Upper, Close[0], 1))
{

Rectangle myRec = Draw.Rectangle(this, "bbTop1"+CurrentBar, 0, Low[0], -10, High[0], Brushes.Transparent);
myRec.AreaBrush = Brushes.LightGray;
}

Hello r3n3v,

Thanks for your post.

Please change your crossabove to: if (CrossAbove(Close, Bollinger1.Upper, 1))

Thanks! I just did and It doesn't always draw the rectangle when price crosses above the bb.

Hello r3n3v,

Thanks for your reply.

Please add a debug print to your code that will print when the cross condition is true. This will help to determine if the condition is the issue or the draw method.

For example:


if (CrossAbove(Bollinger1.Upper, Close[0], 1))
{
Print (Time[0]+" Cross condition true");
Rectangle myRec = Draw.Rectangle(this, "bbTop1"+CurrentBar, 0, Low[0], -10, High[0], Brushes.Transparent);
myRec.AreaBrush = Brushes.LightGray;
}

Before updating the indicator on the chart, open the New>Ninjascript output window to observe the prints when they appear. Once you have print statements compare them to the chart (just a few cases) and see if there is a rectangle drawn at each instance of a print.

I'm only getting 3 conditions on a 5 min chart. It skips these. And the print statement doesn't identify the other times price did cross. I switched it to use arrows down and same thing.

Hello r3n3v,

Thanks for your reply.

I made a mistake with my copy and paste.

Please try:

if (CrossAbove(Close, Bollinger1.Upper, 1))
{
Print (Time[0]+" Cross condition true");
Rectangle myRec = Draw.Rectangle(this, "bbTop1"+CurrentBar, 0, Low[0], -10, High[0], Brushes.Transparent);
myRec.AreaBrush = Brushes.LightGray;
}

[r3n3v]

I actually used that Code...Close.

Hello r3n3v,

Thanks for your reply.

Please replace the CrossAbove() with the following:

if (Close[0] > Open[0] && Close[0] > Bollinger1.Upper[0] && Open[0] < Bollinger1.Upper[0])

Thanks a lot it worked!
