The many uses of the Volume flow indicator VFI clearly displayed in chart examples
1. When VFI is above zero this denotes a
bullish condition. (Trend definition)
2.
When VFI is below zero this denotes a bearish condition. (Trend
definition)
3. As a divergences
indicator,It can be in the usual way as one would use other oscillators
such as Demand Index or Money Flow MFI and Qstick indicators
4. One use not highlighted by most texts is the
use of "V" formations in VFI which when highly correlated with the price
of flag up the trend turning points
in a timely manner. These observations
are best when a dramatic rise of fall in the price and the VFI precede the
V formation.
5. Topping and bottoming
patterns such as head and shoulders and double tops which form in the VFI
often herald a trend reversal in the underlying
instrument before it shows
in the actual price. Pleas see images below.
6.
Rumour has it that Mr Katsanos made $700,000 in a single day from a signal
generated by the volume flow indicator.
7.
As an overbought or oversold oscillator in the same way as RSI
would be used.
8. IMPORTANT NOTE When an
extreme high reading ( overbought ) is observed on the VFI it can often be
an early warning to herald a major uptrend is
starting and traders
entering short on these readings must exercise extreme caution.
9. Obviously the same applies vice versa when
extreme oversold readings occur.

with other volume derived indicators such as
