With options trading (especially with options spreads) one can in advance limit the VaR exactly (or approximately) as one wishes, ie. limiting the possible loss. Let's say you are a daytrader, and each month has 21 trading days. If you make every 2nd trading day on average 1.50% profit from your current account value, but then lose on average 1.00% the following trading day, then how much will your PnL% be in a year? Let's say the very first day is a win day.
What percent does the above scenario calculate out to in terms of daily yield then plug that into this formula. https://elitetrader.com/et/threads/...t-right-here-baby.335635/page-25#post-5537130
That's wrong. One can compute it exactly, for example by simply iterating over all the 12 months, or as @easymon1 said, by using a formula (in this case one can say a period is 2 days, and do accordingly...)
Not sure if you win 1/2 (S1) or 2/3 (S2) of the time. "If you make every 2nd trading day" Monte Carlo is based on S1
