Week of 2012 JL 13

SPY rose by 0.2% this week, while my account rose by less than 0.1%.  This is my third week in a row of gains, which hasn’t happened since last October.  My loss-floor has risen to -7.0%.

New this week: in the “Daily Gains” table, the gain is now shown in green on the first day of ownership (last day still shown in red; I guess orange would be used for day-trades).

Friday’s allocations:

Daily % gain size │ Max loss Sym  Buy │ Fri Mon Tue Wed Thu Fri │ Beg   End   SRTY ¹  JL06 │ -0.2  15  +0.1  15  +0.1  15  +0.1  15  +0.1  0  │ -0.7 -0.7 SRTY ²  JL11 │ +0.2  15  +0.5  16  +0.5  15  │ -0.8 -0.8 TZA  JL11 │ -0.2  15  -0.1  15  -0.6  14  │ -1.2 -1.2 SPY │ +8.0   +7.9   +6.9   +6.9   +6.4   +8.2 │ me │ -7.0 -6.9 -6.9 -6.8 -6.4 -7.0 │ floor │ -7.7 -6.9 -6.9 -8.9 -7.6 -7.0 │

Bugfix: Last week’s NO_MODIFICATION_ALLOWED_ERR was coming from Schwab's function closeAccountSelector(), which responds to any key-event (such as the RETURN I have to send to get past Opera's stupid secure-script warning) by trying to modify the event and then maybe close the account-selector menu. Fixed using window.opera.defineMagicFunction() to override Schwab’s buggy function.  Monday's stop-update was successful, as was Monday's sale and Wednesday’s purchases.  Thursday's stop-update failed due to use of closeAccountSelector() on a different Schwab page (copied over the fix).  Thursday’s and Friday’s sales successful.
