volume indicator


The PVO is the percentage distinction between 2 moving averages of volume. The indicator is measured like this:

PVO = ((Vol 12-day EMA - Vol 26-day EMA)/Vol 12-day EMA) x 100

As you see, the Percentage Volume Oscillator has a maximum value of +100, but no minimum value. The absolute value is not as essential as the direction or the crosses over and under the zero line. The PVO can be used to identify periods of contracting or expanding volume in 3 various ways:

Fluctuations in the PVO are completely separate from price fluctuations. As such, fluctuations in PVO are connected with price fluctuations to assess the degree purchasing or selling pressure. Advances combined with strength in the PVO would be considered strong. Should the PVO decline while a security's price fell, it demonstrates decreasing volume on the decline.
Centerline Crossovers

Like the PPO, the PVO fluctuates above and below the zero line. The shorter EMA of volume is greater than the longer EMA of volume if PVO is positive. The shorter EMA of volume is less than the longer EMA of volume if PVO is negative. A PVO higher than zero indicates that volume levels are generally above average and rather heavy. Volume levels are usually under average and light if the PVO is below zero.

REPULSE VOLUME

En étudiant les indicateurs de volume ,surtout ceux à structure intraday: j'ai imaginé de coupler le Repulse d'Eric Lefort avec l'indicateur volume.

ci-dessous deux codes :le repulsevolume ouvert et le repulsevolume borné.

voici le code :

///REPULSE VOLUME
//avec le code du dernier repulse de 2008

//variable p1 par défaut p1=1

a = 100 * ( 3 * CLOSE - 2 * LOW - OPEN ) / CLOSE
b = 100 * ( OPEN + 2 * HIGH - 3 * CLOSE ) / CLOSE


d = EXPONENTIALAVERAGE[P1](a) - EXPONENTIALAVERAGE[P1](b)

aa=cumsum(d*volume)


RETURN aa as "REPULSE VOLUME"

//////////////////////////////////////////fin


éventuellement le code du Repulse volume borné :


/////////repulse volume borné

//p1 variable du repulse --défaut =1
// p variable periode borne -défaut =10

a = 100 * ( 3 * CLOSE - 2 * LOW - OPEN ) / CLOSE
b = 100 * ( OPEN + 2 * HIGH - 3 * CLOSE ) / CLOSE


d = EXPONENTIALAVERAGE[P1](a) - EXPONENTIALAVERAGE[P1](b)


d1 = d*volume


////////////////bornage

aa=summation[p](d1)

bb=summation[p](volume)


cc = 100 *(aa/bb)


RETURN cc as "repulse volume borné", 0 as "zero"

//////////////fin

Indicatori algoritmici
Ease of Movement (EMV)

L'indicatore Ease of Movement (EMV) stato sviluppato da Richard W. Arms, Jr meglio conosciuto per il popolare indice Arms Index e il metdo grafico Equivolume

EMV = MidpointMove/Box Ratio
Dove Midpoint =(prezzo max di oggi + prezzo min di oggi )/2 -(prezzo max ieri + prezzo min ieri )/2

E:
Box Ratio = Volume /(prezzo max di oggi - Prezzo min di oggi )

Quest indicatore produce un segnale di acquisto quando l'indicatore supera la linea centrale dello zero ed un segnale di vendita arriva quando l'idicatore incrocia la linea passando sotto
