That was a (post-)earnings play on the stock

Weekly Update for week 8/50 ended 03/07/2009 Ugly, ugly week, down 34K (9%). Had my account reset (to starting balance) on Monday and Tuesday with steep losses on CMED, and then trying to anticipate a bounce in the market. Lost 31k in SPY stock and options as the market lacked...

Weekly Update for week 7/50 ended 02/28/2009 Flattish week, up 3.8K (1%). It was a fantastic week on another front with the birth of our baby boy. Spent most of the week on errands, though managed to flip a few trades in between errands. Opening Balance: 363,763...

Weekly Update for week 6/50 ended 02/21/2009 An OK week, up 20K (6%). Makes me look like a genius, considering how terribly I traded: rule violations and missed opportunities. Did fairly OK on Tue, Wed. Then Wed evening bought 2000 shares of PCLN @ 76 after their nice earnings. The...

The exposure to options should be proportional to the square root of the number of days to expiration, subject of course to not exceeding the optimum. The formula used would be f = max(sqrt(daystoexp / 20),1) * g(cratio, histf(strategy), recentf(strategy)). This means if there are 20 or more...

Weekly Update for week 5/50 ended 02/14/2009 Woeful week, down 18K (5%). What started like a good week ended terribly. Was up 20K on Monday after some good trades fading the rally early in the day. Surrendered all that on Tuesday when the market zapped against my positions: was on the...

Mr. Market, Thanks for knocking me out of my positions with a big loss, and then rebounding immediately afterwards. I shall have my revenge!

No fancy indicators. I just keep my eyes open everyday.

You are very correct. Sometimes I get filled on a fraction, and if I do not want to chase the option, that might be it for the trade - with a tiny exposure it is not likely the trade will make it to my top/bottom list for the week. Like I mentioned though, stocks like POT are fairly liquid if...

Yes, I made 17 trades this week, like posted on the journal. The details of the stocks? Sorry, I post only the top/bottom trades.

You will have to divide the quantity column by 100 to get the number of contracts traded. So for SZCNH for this week, it is 600 contracts (representing 60000 shares). For a very liquid option like SPY options it is easy to place a limit order and get all the fills you want. For the particular...

Weekly Update for week 4/50 ended 02/07/2009 Another nice week, up 25K (7%). Pleased there were no stand-out losers except the SPY put on Friday. Incidentally biggest gainer was POT put on the same day. Emphasis this week was reducing risk through reduction in holding time frame. While it...

If you look at my prior sizing analysis, I should take smaller risk (position size) as my account size is just too close to my starting capital (that must be protected at all cost). Still working on completing and putting into effect my position sizing rules.

Wouldn't classify myelf as such. Look at everything including price! SPY tells me everything if looking at the day from a bigger perspective (market). Have no interest in diversifying to other indexes. Add liquidity as well.

95% of my trades these days are intra-day

Weekly Update for week 3/50 ended 1/31/2009 Nice week, up 25K (8%). Very good win rate (80%). Lots of trades on SPY as well, with a tendency to exceed my intended size because of averaging up/down: biggest was 8K on Monday, while I lost almost as much on the same SPY earlier. The market...

Continuing on the development of the sizing formula. The first variable is cratio. The idea is to shrink my position size when there is little or no buffer, and to size up to the optimal as the buffer increases. With that in mind, I have found the formula below good: f =...

Weekly Update for week 2/50 ended 1/24/2009 Moderately positive week, up 9.6K (3.2%). Made it Tues/Wed, lost it Thur, and gained some back on Friday. The market is definitely begging for direction. Opening Balance: 301,530 Net gain for the week...

Undeniable if all you have is $25K to start with. If you are a multi-millionaire, the difference in feeling is negligible

Nope. One week is too myopic a time-frame to work towards. The fear of losing for the week would cause me not to take any risk, and with that have a flat curve.
