Week of 2014 JL 11

IWM fell by 4.1% this week, while my account fell by 1.7%.  The loss-floor has risen to -7.0%.

For the year-to-date, the IWM basket of small-caps is flat, while my account balance is down about 5% — but my loss-floor is down only ½% since the start of 2014.

End of week allocations: 15% equities, 32% silver, 58% cash

AGQ: The last six weeks have seen the biggest run-up in silver of the last three years!  And I’ve been in on it for the last four of those weeks, all gainers, including the week of JN 20 which was a big gainer.

Stock-trading robot

As a side-effect of other stuff I did last week, the daily fixups (replacing Schwab prices with Barchart prices) did not run.  This caused various IWM-derived trades to occur at the wrong times.  Also, IWM declared a dividend on JL 02, but I did not update the price-database until this weekend — this caused a smaller but still noticeable divergence between my calculated “model” results and the visual results shown on Stockchart.com’s charts.  Results shown below are for the corrected data.

Another problem: this week there were many quote-fetch failures, apparently caused by some random change to Schwab’s login page.  I put in some error-recovery code and now it seems to be working.

UWM: Too bad I skipped this trade, which would have been profitable.  But I just didn’t have any spare cash available on JN 02.

URTY: Late sale due to bad data in database.  The buy and sell prices were both better than model, yet net profit was less than expected???  Managed to keep only 0.7% of the peak 2.0% gain that this trade once had.  Still, it’s a gain!

ATML: Trade execution was perfect in time and price!  And this small win follows the big winner trade in ATML from May to June.  And there’s a “Buy” signal for ATML for next Monday.

FRED ¹: Once again the robot traded this stock a day earlier than the model now says it should have.  This was apparently caused by a duplicate quote for JN 11 that got into the robot’s database.

TNA: Reached break-even before stopping out.  Stop-price calculation was apparently a little high, which worked out in my favour.

SRTY ¹: Robot failed to fetch quotes from Schwab at 11am and 12pm on Tuesday, postponing this purchase.  On Wednesday, robot failed to fetch a quote at 10am so I sold manually.

SRTY ¹: More missed quotes, leading to a manual sale that was “late” due to bad data in the database — corrected data says I shouldn’t have sold yet.

FRED ²: Didn’t like the looks of the chart when the robot said to buy it on JL 10, so I didn’t bother entering this trade.  Since then it’s done nothing but go down.

YHOO: Chart looked better, so I put in the buy-limit order.  So far, so good!
