SMA extension

I know this is an odd question, but is it possible to extend the SMA 20 bars out? If so, how? Here is the SMA script. Any help is appreciated.

Code: 
input price = close;
input length = 9;
input displace = 0;
input showBreakoutSignals = no;

plot SMA = Average(price[-displace], length);

i tried adding the following code to return the bar number but its not working.

Code: 
def crossing_bar = if close and extension crosses  extension2 then BarNumber() else crossing_bar[1];
AddLabel (yes, "crossing bar" +  (crossing_bar)  );

If i can get the bar number i can get the price its at but i must first get the bar number and the code isnt working. Im not really to familiar with extending to the right where there is are no bars to retrieve data. Perhaps @SleepyZ can chime in and help.

Code:

plot x    = if barnumber()==highestall(cross) then extension else double.nan;
x.setpaintingStrategy(PaintingStrategy.ARROW_UP);

nice work SleepyZ, i battled that for like 30 mins going crazy trying to figure it out, i used double.nan too but was strange the label wouldnt record the number.
even with your code Cross wont return the bar number on a label as the example above. thats strange, thats what had me stumped, i still dont understand why it doesnt. but i guess if the code is properly coded and finished like you did it then the final code works. thats strange. im baffled as to why cross doesnt return barnumber value in
AddLabel (yes, "TEST " + (cross) );
yet it still works correctly for final code.

all my previous codings for getting barnumber always returns a value in the label when testing if i have it coded right....this is coded right but the bar number value doesnt show, super strange.

Sometimes the extensions do not cross within the extended chart area, causing no values for the labels. When a cross is present, this should produce values for your labels.
Code: 
AddLabel (yes, "TEST " +  highestall(cross)  );
AddLabel (yes, "Cross " +  (highestall(x))  );

Huge thank you to everyone who contributed their time and effort on this! XeoNox and SleepyZ especially. I will be using this through the week. Definitely excited to see how this works.

the extension value doesnt refresh itself. i had to change the timeframe of the chart and come back then it shows the value. otherwise it is stuck. Any idea what could be done? TIA

I’m not really sure. I haven’t used the SMA extension indicator really. I do use the version with the STARC band extensions all the time though. I haven’t had trouble with that version. I’m sorry I can’t be of more help.

Thanks a lot for the response. The best way to solve this problem is to somehow refresh the chart. Any idea how we can do that? TIA

Hi Christopher84,

Just had a quick question. How exactly are you using the cross? Can you please elaborate?

Any help and guidance is highly appreciated.

Thank you in Advance

Hi chinks1980!
When I see a consistent zone where the extensions are crossing, it can indicate support/resistance zones as well as directionality of future price movements. More than anything, I look for the extensions to agree on direction and not be crossed. When this happens price will be moving the indicated direction. When the extensions cross, especially when their direction is contradictory (one up and one down), price movement will start to stagnate and potentially shift into a reversal.

Is it possible to have the extension color dynamically base on the slope of the current average? AssignValueColor will only work on the current bar (won't color into the future), and setdefaultcolor will color into the future, but it doesn't allow for dynamic coloring based on slope. Have any thoughts on how to do this?

Tried various scenarios w/ [-1] and isNan, etc.. My conclusion is that there is not the capability for dynamic conditional coloring
