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).

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.
