value = riskAdjustedRatioParameter.BeginValue
riskAdjustedRatioParameter.BeginValue = value

The initial value of the parameter.

Period

public TimeSpan Period { get; set; }

value = riskAdjustedRatioParameter.Period
riskAdjustedRatioParameter.Period = value

RiskFreeRate

public decimal RiskFreeRate { get; set; }

value = riskAdjustedRatioParameter.RiskFreeRate
riskAdjustedRatioParameter.RiskFreeRate = value

Jährlicher risikofreier Zinssatz (e.g., 0,03 = 3%).

Add

public override void Add(DateTime marketTime, decimal pnl, decimal? commission)

riskAdjustedRatioParameter.Add(marketTime, pnl, commission)

Um neue Daten zum Parameter hinzuzufügen.

marketTime

Die Austauschzeit.

pnl

Der Gewinn-Verlust-Wert.

commission

Kommission.

AddRiskSample

protected abstract void AddRiskSample(decimal ret, long count)

riskAdjustedRatioParameter.AddRiskSample(ret, count)

Adds consecutive periods of the same return to the risk accumulator.

ret

The return value.

count

How many periods earned it.

AddSample

private bool AddSample(decimal start, decimal level, long count)

result = riskAdjustedRatioParameter.AddSample(start, level, count)

Records periods that opened on and closed on .

start

The PnL level the periods opened on.

level

The PnL level they closed on.

count

How many periods earned that return.

Rückgabe: if the return was recorded; if there was no capital to measure it against.

ClosePeriods

private bool ClosePeriods(long target, decimal level)

result = riskAdjustedRatioParameter.ClosePeriods(target, level)

Closes every grid boundary up to on the given PnL level.

target

The number of boundaries the grid is to have closed.

level

The PnL level those boundaries close on.

Rückgabe: if every closed period produced a return; if any of them had no capital to measure a return against.

GetRisk

protected abstract decimal GetRisk(long count, decimal sumReturn)

result = riskAdjustedRatioParameter.GetRisk(count, sumReturn)

Gets the risk value (e.g., stddev or downside deviation).

count

Count of samples.

sumReturn

Sum of all returns.

Rückgabe: Risk value.

HasEnoughRiskSamples

protected abstract bool HasEnoughRiskSamples(long count)

result = riskAdjustedRatioParameter.HasEnoughRiskSamples(count)

Checks if enough risk samples accumulated for calculation.

count

Count of samples.

Rückgabe: Check result.

SetPeriod

private void SetPeriod(TimeSpan value)

riskAdjustedRatioParameter.SetPeriod(value)

Sets Period without the open-grid check, for restoring a state that was saved with it.

value

Return calculation period.
