This indicator is the smoothed standard indicator Average .
It has five adjustable parameters:
- Period – ADX calculation period
- Primary smoothing factor – primary factor of smoothing
- Secondary smoothing factor – secondary factor of smoothing
- Strong trend level – level of a strong trend
- Weak trend level – level of a weak trend
Calculations:
SDIP = Secondary smoothing factor * DIPtmp + (1.0 – Secondary smoothing factor) * PrevSDIP
SDIM =Secondary smoothing factor * DIMtmp + (1.0 – Secondary smoothing factor) * PrevSDIM
SADX = Secondary smoothing factor * ADXtmp + (1.0 – Secondary smoothing factor) * PrevSADX
where:
DIPtmp = 2.0 * DMIplus + (Primary smoothing factor – 2.0) * PrevDMIplus + (1.0 – Primary smoothing factor) * PrevDIPtmp
DIMtmp = 2.0 * DMIminus + (Primary smoothing factor – 2.0) * PrevDMIminus + (1.0 – Primary smoothing factor) * PrevDIMtmp
ADXtmp = 2.0 * ADX + (Primary smoothing factor – 2.0) * PrevADX + (1.0 – Primary smoothing factor) * PrevADXtmp
DMIplus, DMIminus – DMI+ и DMI-
