Indicator Description

EMV (Ease of Movement) is a technical indicator that combines price and volume to measure the ease of price movement and reflect market supply and demand.

Function Information

• Function Name: EMV
• Input Parameters: High, Low, Volume
• Parameter Settings: timeperiod1 (default: 13), timeperiod2 (default: 8)
• Output: mv, emv, emva

Calculation Principle

EMV is calculated using the following formula:

MidPoint = (High + Low) / 2
MidPointMove = MidPoint - MidPoint[-1]
BoxRatio = Volume / (High - Low)
EMV = MidPointMove / BoxRatio
EMVA = MA(EMV, timeperiod2)

Where MidPoint[-1] is the previous midpoint and MA is the moving average.

Usage Scenarios

1. Market supply and demand analysis
2. Price movement ease judgment
3. Volume effectiveness verification
4. Trend strength confirmation

Usage Recommendations

1. EMV turning from negative to positive can be seen as a buy signal
2. EMV turning from positive to negative can be seen as a sell signal
3. Use in combination with price trends
4. Pay attention to volume coordination

Notes

• Parameter settings affect indicator sensitivity
• May be distorted in low-volume markets
• It is recommended to use in combination with other technical indicators
• Pay attention to changes in market environment
