Why you need it
A move looks strong: green candles, price climbing. But you cannot tell if real upward volatility carries it, or if it creeps up in small steps while the larger swings point down. A normal volatility reading shows how big the moves are, not which side drives them. You enter, and the pressure was on the other side.
What you get
Fabii Volatility Bias is a directional volatility histogram that shows which side, up or down, carries the volatility.
- One histogram between -1 and +1 that compares upward and downward volatility, so you read the pressure at a glance.
- Green above zero, Red below zero and Gray inside a deadzone around zero, so small fluctuations do not flip the color.
- A higher timeframe option that reads the closed candles of a larger timeframe, so you see the bigger bias on your chart.
- Popup, sound and push alerts when the bias turns bullish or bearish on a closed bar, so you do not have to watch the screen.
- Two buffers readable from an Expert Advisor, the bias value and a three-state value, so you can build your own rules.
How it works
The indicator splits the price changes of the last 20 closed bars into upward and downward moves, then adds up the squared size of each group. The difference between the two sums, divided by their total, is the bias, so the histogram always stays between -1 and +1. Positive means upward volatility dominates, negative means downward volatility dominates, and values near zero fall in the Gray deadzone. Closed bars never change. The bar in progress is drawn in a separate provisional plot and replaced by its final value when it closes.
How to use it
- Attach the indicator to any chart.
- Read the color: Green means upward volatility dominates, Red means downward volatility dominates, Gray means neither side leads.
- Use it as a filter for your own setups: look for longs when it is Green, shorts when it is Red, and wait when it is Gray.
- Turn on the alerts you want, so you are notified when the bias turns bullish or bearish.
