Hi
Fat Tails
I think this price volume analysis index is better.Can you help me compile it into ninja8 indicator?
THANK YOU !!

Could you give us a brief description with a few screenshots to show how it works?

I use it on the range chart.Do you find it useful?
I think this is like a kind order flow.
Forgive me for poor English.
and i can't pm you .Because my level is not enough

This seems to be a range chart. The indicator logic is not compatible with range charts, as it basically performs volume spread analysis. If you use it with a range chart, the spread is always the same and it cannot work as intended.

User Notes:

This indicator is coded to run on MT4 Build 600+. It draws PVA (Price-Volume Analysis) bar
and candlestick charts.

PVA Bars & Candlesticks -
The PVA bars and PVA candlesticks are used together with PVA volume for easy recognition of
when special price and volume situations occur. The special situations, or requirements for
the colors used are as follows.

Situation "Climax"
Bars with volume >= 200% of the average volume of the 10 previous chart TFs, or bars
where the product of candle spread x candle volume is >= the highest for the 10 previous
chart time TFs.
Default Colors: Bull bars are green and bear bars are red.

Situation "Volume Rising Above Average"
Bars with volume >= 150% of the average volume of the 10 previous chart TFs.
Default Colors: Bull bars are blue and bear are blue-violet.

PVA Color Options -
There are two PVA color options provided by "Color_Custom_Default_12".
1. Custom: Use this option for the multi-color PVA display where you can change colors.
This option is to help those suffering from color blindness or with other reasons for
needing different colors that better suit them.
2. Default: There are no inputs. The traditional multi-color PVA display is hard coded.
You can easily return to this display anytime while preserving those changes made to
the Custom display.

Selecting the Type of PVA Price Display -
To show PVA bars set "Style_Bars_Candles_12" to "1". To show PVA candlesticks input "2".
These bars and candlesticks display on top of the solid color Trend. A proper display
requires the MT4 price display be "Line chart" with CLR_NONE" as color, and not be set to
foreground. Be sure that chart Properties/Common tab/Chart on foreground is NOT checked!

This seems to be a range chart. The indicator logic is not compatible with range charts, as it basically performs volume spread analysis. If you use it with a range chart, the spread is always the same and it cannot work as intended.

I don't understand a bit. Is its volume calculation based on bars?range chart is bars too,why is not compatible.

When you perform volume spread analysis (VSA) then you look for high volume bars and wide range bars. How would you identify a wide range bar on a range chart where all bars have the same range?

Basically the concept of VSA can only be applied to time based bars and - to some extent - to tick and volume bars. But it definitely fails when analyzing range or renko charts.

The same applies to volatility based stops such as the ATR Trailing Stop, the Wilder Volatility Stop, the Chandelier Stop or the SuperTrend. The volatility based stop is designed to widen when volatility is high and to get closer to price when volatility decreases. All these stops use the average range or average true range to measure volatility. However, on a range chart the average range and the average true range do not change when volatility changes and remain the same all the time.

Therefore these volatility based stops become fixed trailing stops on a range chart, which is definitely not what they have been designed for.

I still don't understand very well. haha
But I am looking forward to your new work.
Can you send me a copy when you are done?
