Imagine you are a high level finance student trying to create a Basel Traffic Light graph on excel. You have the number of exceedances for the following VaR models: The normal rolling window $252$ and $66$ days, the EWMA $(0\mathrm{.}94),$ the historical simulation $($not rolling window$)252$ and $66$ days. Can you please guide me in creating this graph on excel. Keep in mind, the models that require more than $252$ days should be calculated starting from day $253($professor$\text{'}$s instruction$).$ The current dates goes from newest $($top$)$ to oldest $($bottom$).$
