Modified TradingView's Up/Down Volume [vnhilton]

When plotting columns, histograms, etc. You'll notice that the indicator does not stick to the bottom of the pane. To fix this, you need another indicator (we'll call this 'placeholder') in the same pane as this indicator. Pin the placeholder indicator to the left scale, & pin the main indicator to the left scale. Then, pin the placeholder indicator to scale A, & finally the main indictor to the right scale.

Note: On the daily timeframes & higher, the up/down volume isn't accurate. Therefore, I've added a feature where you can toggle on the main indicator to disappear & only show ordinary total volume similar to the TradingView volume indicator.

The original code belongs to TradingView. This is a modified indicator that displays the down volume above the up volume similar to the volume profile. Also includes a moving average using the total volume, & a feature to display ordinary volume to solve the up/down inaccuracies on the daily timeframe & higher.

- Added "Proportionality Estimation": This applies a multiplier to up volume & down volume to estimate the day up volume & down volume. This feature is mainly for those who don't have extra market data, & still want to see somewhat accurate up/down volume on the daily.
- Fixed ordinary volume (previously used intraday data to decide volume but this was incorrect application)
- Adjusted moving average to take into account new feature
