Code:

```
input price = close;
input length = 9;
input displace = 0;
input showBreakoutSignals = no;
plot SMA = Average(price[-displace], length);
```

Solution

Code:`declare weak_volume_dependency; input price = close; input ATR_length = 15; input SMA_length = 6; input displace = 0; input multiplier_factor = 1.5; def val = Average(price, sma_length); def average_true_range = Average(TrueRange(high, close, low), length = atr_length); plot Upper_Band = val[-displace] + multiplier_factor * average_true_range[-displace]; Upper_Band.SetStyle(Curve.SHORT_DASH); Upper_Band.SetLineWeight(2); Upper_Band.SetDefaultColor(Color.Gray); def Middle_Band = val[-displace]; #Middle_Band.SetDefaultColor(GetColor(1)); plot Lower_Band = val[-displace] - multiplier_factor * average_true_range[-displace]; Lower_Band.SetStyle(Curve.SHORT_DASH); Lower_Band.SetLineWeight(2)...`

is it possible to extend the SMA 20 bars out?

What do you mean by that?

Similar to the line extensions available when using the drawing feature except on sma instead of a static line. I was hoping to extend the line 20 bars forward.What do you mean by that?

Well sma, means simple moving average, you can't extend something that doesn't exist yet, meaning there's nothing to average yet, however you can push the present moving average onto the futureSimilar to the line extensions available when using the drawing feature except on sma instead of a static line. I was hoping to extend the line 20 bars forward.

I understand what sma means. I do not want to displace it into the future. I want to extend the end of it using its current slope.Well sma, means simple moving average, you can't extend something that doesn't exist yet, meaning there's nothing to average yet, however you can push the present moving average onto the future

Look at the

Code:`input price = close; input length = 9; input displace = 0; input showBreakoutSignals = no; plot SMA = Average(price[-displace], length);`

Here is an example from Mobius

Code:

```
# Plotting MA slope into extension area
# Mobius
# Chat Room Request
input n = 10;
input AvgType = AverageType.SIMPLE;
input price = close;
def MA = if !IsNaN(close())
then MovingAverage(AvgType, price, n)
else MA[1] + ((MA[1] - MA[n]) / (n - 1));
plot data = MA;
```

I added on to Mobius's code, all credits to him, i incorporated inertia plus made it so it uses the more recent data.

**Plotting MA slope into extension area (Modded) .. **__All original credits to MOBIUS__

Draws extended line to the right of the chart based off recent linear regression curve of the Moving Average

That is exactly what I am looking for! Thank you so much for your help!!!def inertline = inertiaall(moveavg,2); def EXT_MA = if !IsNaN(close()) then inertline else EXT_MA[1] + ((EXT_MA[1] - EXT_MA[2]) / (2 - 1)); plot extension = EXT_MA; extension.SetDefaultColor(CreateColor(0, 255, 255)); extension.SetLineWeight(1);

If I wanted to limit the extension length to 20 bars, what would be the correct way to code that?

BTW @Christopher84 in your original post you said it was a odd question, i just would like to let you know your question really wasnt odd at all, i find this possibly being very useful. To be honest with you ive drawn them manually in the past if i needed to.

If you want the extension's value (possibly as a price projection) as a label just add this code to SleepyZ's code above in post #13

If you want the extension's value (possibly as a price projection) as a label just add this code to SleepyZ's code above in post #13

Code:

`AddLabel (yes, "Extension End: " + round(highestall(extension),2) );`

That did the trick! Thank you for sharing. I modified the code to work on the STARC Bands. It looks a bit like headlights on a car. It helps to show volatility and directionality (including reversals). I really appreciate the help.See if this helps

I’m glad to know I’m not the only one trying to draw them in. lol Would it be possible to have a point plot on the chart where the two extensions are crossed?

youll have to post a screenshot of what you mean. and what do you mean by point? a arrow?I’m glad to know I’m not the only one trying to draw them in. lol Would it be possible to have a point plot on the chart where the two extensions are crossed?

I think that the crossing points of the STARC Band extensions may show support and resistance zones. I’m wanting points or maybe dashes to show the zones. When I get to the office this morning, I’ll post the code if you think it’s a possibility.youll have to post a screenshot of what you mean. and what do you mean by point? a arrow?
