Golang DOHLCV.V Examples

Example #1

File: adl.go Project: jmptrader/gotrade

// ReceiveDOHLCVTick consumes a source data DOHLCV price tick
func (ind *AdlWithoutStorage) ReceiveDOHLCVTick(tickData gotrade.DOHLCV, streamBarIndex int) {

	moneyFlowMultiplier := ((tickData.C() - tickData.L()) - (tickData.H() - tickData.C())) / (tickData.H() - tickData.L())
	moneyFlowVolume := moneyFlowMultiplier * tickData.V()
	result := ind.previousAdl + moneyFlowVolume

	ind.UpdateIndicatorWithNewValue(result, streamBarIndex)

	ind.previousAdl = result
}

Example #2

File: obv.go Project: jmptrader/gotrade

// ReceiveDOHLCVTick consumes a source data DOHLCV price tick

		result := ind.previousObv

		ind.UpdateIndicatorWithNewValue(result, streamBarIndex)

		result := ind.previousObv

		ind.UpdateIndicatorWithNewValue(result, streamBarIndex)

		ind.previousClose = tickData.C()
	}
