# MoneyFlow

### Syntax

```public MoneyFlow(Bars bars, string description)
public static MoneyFlow Series(Bars bars)
```

### Parameter Description

 bars The Bars object

### Description

Money Flow returns the average price multiplied by volume. Money Flow is the core component of the Money Flow Index (MFI) indicator. This is not really an indicator, but a mathematical function used to construct other indicators.

### Interpretation

See the Money Flow Index (MFI) indicator and the example strategy application below.

### Calculation

Money Flow is the average price multiplied by Volume.

Money Flow = Volume x AveragePriceC

### Example

```using System;
using System.Collections.Generic;
using System.Text;
using System.Drawing;
using WealthLab;
using WealthLab.Indicators;namespace WealthLab.Strategies
{
public class MyStrategy : WealthScript
{
protected override void Execute()
{
// The example below duplicates the calculation of the MFI
double today = 0;	double yesterday = 0;
DataSeries MFPositive = new DataSeries( Bars, "MFPositive" );
DataSeries MFNegative = new DataSeries( Bars, "MFNegative" );
DataSeries MyMFI = new DataSeries( Bars, "MyMFI" );
DataSeries myAveragePrice = (High+Low+Close)/3;

for(int bar = 1; bar < Bars.Count; bar++)
{
today = myAveragePrice[bar];
yesterday = myAveragePrice[bar-1];
if( today > yesterday )
MFPositive[bar] = MoneyFlow.Series( Bars )[bar]; else
if( today < yesterday )
MFNegative[bar] = MoneyFlow.Series( Bars )[bar];
}

DataSeries MFPosSum = Sum.Series( MFPositive, 14 );
DataSeries MFNegSum = Sum.Series( MFNegative, 14 );
DataSeries MoneyRatio = MFPosSum/MFNegSum;			for(int bar = 14; bar < Bars.Count; bar++)
MyMFI[bar] = 100 - ( 100 / ( 1 + MoneyRatio[bar] ) );

ChartPane MFPane = CreatePane( 30, true, true );
ChartPane MFIPane = CreatePane( 30, true, true );
PlotSeries( MFPane, MyMFI, Color.Navy, WealthLab.LineStyle.Solid, 2 );
PlotSeries( MFIPane, MFI.Series( Bars, 14 ), Color.Brown, WealthLab.LineStyle.Solid, 2 );
}
}
}```
