Better Volume Indicator [BVI]
-----------------------------------------
This is a direct port of a famous indicator from Tradestation platform.

BVI improves on your typical volume histogram by coloring the bars based on 5 criteria:
* Volume Climax Up – high volume, high range, up bars (red)
* Volume Climax Down – high volume, high range, down bars (white)
* High Volume Churn – high volume, low range bars (green, barcolor= blue)
* Low Volume – low volume bars (yellow)
* Volume Climax plus High Volume Churn – both the above conditions (magenta)

When there are no volume signals the default histogram bar coloring is cyan.

Bars can also be colored to match volume color. Enable "Change BarColors?" in the options page.

Volume Climax Up bars are typically seen at:
* The start of up trends
* The end of up trends, and
* Pullbacks during down trends.

Volume Climax Down bars are typically seen at:
* The start of down trends
* The end of down trends, and
* Pullbacks during up trends.

High Volume Churn bars are typically seen at:
* The end of up trends
* The end of down trends, and
* Profit taking mid-trend.

Low Volume bars are typically seen at:
* The end of up trends
* The end of down trends, and
* Pullbacks mid-trend.

Instrument Volume
-----------------------------------------
This is a simple script that allows you to plot volume for any instrument.

Very handy when you want to compare volumes. Just add multiple instances and select the symbol you want via Options page.

This script also gets close/open for the selected symbol. If you are itching to get started on Pinescripting (scripting language used at TV), I suggest trying out the following, using this script as the template:
- Show RSI for any instrument
(hint: "close" for the selected symbol is already in script. Do a "plot(rsi(c, 14))")
- MACD / CCI / ....
- Plot the difference (not correlation). This may be of interest in some instruments.
For ex. BTC in BTCE exchange mostly lags BITSTAMP.

Hope this piques your interest in Pine. Feel free to post in the Pinescript room if you have any queries.
