Indicator: STARC Bands

3065 12 269
STARC (Stoller Average Range Channels) bands make use of ATR to form the bands, giving it a more in-depth snapshot of market volatility compared to Bollinger Bands .

When a price curve penetrates a Bollinger Band , it may indicate the continuation of a price move; in contrast, the STARC bands tend to define upper and lower limits for normal price action.

Another trick I have seen suggested is to render both STARC and BB.

For ex.

Hi there, and thank for continuing efforts.

Just one comment -- Keltner channel (standard TV indicator also uses ATR around moving average. Is there any difference?

They are both the same when it comes to theory -- ATR with a multiplier added/subtracted to a median. Median is usually SMA in SB, while EMA (or typical price, if you want the pure formula) in KC.

Here's a comparison.

BTW, if you scroll down my published charts page, I published an implementation of KC too (way before TV addition). The params I prefer are different from stock TV indicator, of course.

Ok, it seems to I see the difference.

Your indicator is basically ATR added and substracted to the price.

Keltner channel is ATR added and substracted to the moving average.

"Basis" is a SMA, not price as-is. Length suggested for SB is 5.

Third, and hope last comment -- I just check Keltner channel with

Length = 8
Multiplyer = 2
Exponential = x

and the result is very close to STARC.

Regarding the strategy buying the lower band and selling the upper is considered lousy by people working with Keltner. At least in the simplest form. That's what I heard from traders.

Anyways, fascinated with your research and appreciate it.

Click on the "Share" button on my chart (right top -- looks like an arrow). A dialog box opens up. Click on "Make mine". You will get a copy of my published chart. It has the source code. (click in "{}" icon next to the name of the indicator).
