This online tool aims to compute the Value-At-Risk according to the Historical approach.
It needs as input a CSV file containing the following information : Date, TradeID, P&L Vector.
For further details about the measure computation or the configuration - please see the related section below.
Value-At-Risk represents an investor's maximum potential loss on the value of a financial asset or portfolio of assets, which is expected to be achieved only with a given probability over a given time horizon.
It is, in other words, the worst expected loss over a given time horizon for a given level of confidence.
VaR can be seen as a quantile of the profit-and-loss distribution associated with holding an asset or a portfolio of assets over a given period.
This tool is computing the VaR, according to the Historical approach.
The method used to compute the index of the quantile.
Knowing q the quantile of a vector V, available options are :
If the quantile index is not an integer, the interpolation decides what value is returned.
Knowing a quantile index k with i<k<j for the sorted vector V.
