That's really funny, Jack. Because DD is irrelevant in this kind of trading of mine. In one of the postings yesterday I gave the reason. DD can be "fixed" (or manipulated) easily... Ie. IMO in this case a meaningless metric...
And: I repeat for the 1 millionths of time: I'm not daytrading!... I'm over over such childish and silly metrics... I mean in my case DD/MDD is irrelevant... Forget it...
Also please dont start with the next one: VaR etc. All nothing but crap metrics, much like TA and FA... What counts is just the realtime price action, nothing else... Ie. in my case the said "sell high, sell much" principle...
From this simple fancy barchart (NAV time series) you should be able to derive the daily DD you mean:

I'll post tomorrow (or monday) an update of it.
Btw, I can encourage all people to study the orderbook, it's so simple, and the knowledge of it so powerful and useful for own trading... That's the place where all meet, incl. the MMs...
Just out of interest, and in regards the broker IB.
If Mars can do as he says, would IB pick up on his excellent trading skills and then copy them?
Or is a broker not allowed to piggyback his clients? I'm not saying they would front run his orders (but I'm sure some brokers do) but perhaps tag on with his orders.
IB is probably one of the most legit brokers out there but then this is the financial markets we're talking about and they're known for their crookiness.
So, you mean the MM rises the Ask and lowers the Bid?
Then people who entered positions some days/weeks ago will be happy....
It doesn't sum up, man!
Here's an example:This has to be the silliest comment ever... drawdown is irrelevant... hahaaa tell that to your risk manager.
@HappyTrader, it seems you have a different meaning of the word "margin".
In this kind of trades (options short selling) you can't use any margin of the broker, rather you have to bring the margin yourself as a collateral from your own cash in your acount.
Then you have to base the expected (and also the realised) profit based on that very investment of yours.
I suggest you learn the margin requirement formulae for naked calls and puts, as well the combination of them, ie. the margin requirement for short strangle etc. on this page:
https://www.interactivebrokers.com/en/index.php?f=marginnew&p=opt
And: in TWS you can preview the margin requirement before submitting the trade.
And: the margin requirement is dynamic, ie. the broker adjustes it constantly (I think even realtime), s. "maintenance margin requirement" in margin handbook etc.
Regarding portfolio profit calculation: currently I've calculated it simply based on the account value at end in relation to account value at start...
In case of a loss on the short-call side you have to deliver the stock based on the strike price.
In case of a loss on the short-put side you have to buy (ie. take) the stock based on the strike price.
Of course if possible you would want to apply some hedging to minimize a loss. This hedging
can be done anytime, and one has multiple possibilities: stock or other options... What counts is the net result...
Regarding the probabilities: these are just guestimates based on experience and expectation, not an exact science.
Maybe other people can help you more than I as I don't have much time, sorry...
