URTY ¹: Another completed trade using the new trading model!  Minimal profit, and bought it back two days later for more money, so not the best move.

AGQ: Another completed trade.  Not a huge loss, but it ate up all of this week’s profits from the other tickers.

PPO-based swing trades

Retuned using the new archival data.  Yellow below indicates changes from the table given on 2012 JL 20.

Bull swing (TNA)	Bear swing (TZA)

Alternate buy signal:
(None)	Time = 10am–3pm, on the hour This hour’s price < SMA(74) This hour’s PPO(10,60,8) minus its value from 20 hours ago < -1.55 It has been at least 2 hours since last sale.
Buy-more signal:
Time = 10am–4pm, on the hour Either PPO(8,73,12) has risen by at least 0.001 during each of the last two hours PPO(8,73,12) has changed by less than ±0.001 during the last hour and rose by at least 0.001 during each of the preceding two hours PPO(8,73,12) fell by at least 0.001 during the two hours before that. STDDEV(81) < its EMA(8) Have bought no more than 1 tranche so far If signal received at 10am or 4pm, postpone purchase to 11am	Time = 10am–4pm, on the hour Either PPO(10,60,8) has fallen by at least 0.015 during each of the last two hours PPO(10,60,8) has changed by less than ±0.015 during the last hour and fell  by at least 0.015 during each of the preceding two hours PPO(10,60,8) rose by at least 0.015 during the two hours before that. STDDEV(33) < its EMA(4) Have bought 3 or fewer tranches so far If signal received at 4pm, postpone purchase to 10am 10am or
Sell signal:
Time = 11am–3pm, on the hour 99.9%  of this hour’s price < previous hour’s price This hour’s PPO(8,73,12) < -0.41 PPO(8,73,12) has gone above +0.16 since original purchase	Time = 10am–3pm, on the hour 100.1% of this hour’s price > previous hour’s price This hour’s PPO(10,60,8) > +0.15 PPO(10,60,8) has gone below -0.05 since original purchase

Time = 11am–3pm, on the hour This hour’s PPO(8,73,12) minus its value from 20 hours ago < -2.95 It has been at least 0 hours since last purchase.	Time = 10am–3pm, on the hour This hour’s PPO(10,60,8) minus its value from 20 hours ago > +1.3 It has been at least 2 hours since last purchase.
Stop update:
Time = 10am Calculate new stop = lowest price seen in preceding 22 hours. Raise new stop to 0% of the highest price seen in preceding 22 hours, if less than that If I don’t currently own TNA, replace stop with the newly-calculated value.  Otherwise: Discard new stop (and keep the old one) if the new value is lower Sell now if lowest price of last 22 hours occurred during the last hour Otherwise, convert the IWM-based stop to the corresponding TNA price and update the standing stop-order at Schwab	Time = 10am Calculate new stop = highest price seen in preceding 22 hours. Lower new stop to 105.5% of the lowest price seen in preceding 22 hours, if greater than that If I don’t currently own TZA, replace stop with the newly-calculated value.  Otherwise: Discard new stop (and keep the old one) if the new value is higher Sell now if highest price of last 22 hours occurred during the last hour Otherwise, convert the IWM-based stop to the corresponding TZA price and update the standing stop-order at Schwab

For TNA, some of these revised parameter values cause the corresponding feature to be disabled.  SMA(1) is always equal to the current price, so this clause will never block a purchase.  This hour’s PPO(8,73,12) minus its value from 20 hours ago must be > 99, which disables the alternate-buy rule.  The stop is raised only if it is 0% of the price, which disables the trailing-stop element of the rule.

Below is a comparison of the old and new parameter-sets.  The old parameter-set was tuned on 2008‥2011, while the new one was tuned on 2002‥2011.  The “All” column assumes that I invest 300% of my money in IWM, while the two “TNA” columns assume that I invest 30% of my money in IWM (but actually 10% in TNA), while the “TZA” columns assume that I hold a 30% short position in IWM (but actually I will go 10% long TZA).

				TNA			TZA
		All		old	new		old	new
2003		135%		1.6%	6.6%		-0.2%	0.5%
2004		51%		5.0%	7.0%		-1.6%	0.7%
2005		9%		0.7%	-1.7%		0.1%	0.2%
2006		51%		-1.5%	-3.2%		-3.2%	-1.3%
2007		-6%		-1.1%	0.8%		-3.6%	-0.2%
2008		-114%		10.5%	8.5%		20.5%	24.9%
2009		99%		4.1%	14.9%		2.7%	1.6%
2010		69%		11.6%	9.6%		8.1%	5.6%
2011		18%		8.0%	8.4%		15.3%	13.2%
2012		36%		2.6%	-2.0%		-3.1%	-0.9%
TOTAL		351%		41.9%	52.4%		35.5%	44.7%

Note that both old and new tunings for both tickers show multi-year periods of losess!  The new TNA model would not have done well in either 2005 or 2006, while the new TZA model would have done badly in 2006 and 2007.  Also note that both retuned models show losses for 2012.

Gold trading

Still no “Buy” signal.  Weekly MACD(14,25,9) = -0.01, but I want to see a positive value.  Keep waiting.

URTY ¹: Once again, got very little profit because I was very late to a trade-already-in-progress.  Still, got a profit!

AGQ: Stopped out.  Robot functioned properly, but this trade happened to be a loser.

URTY ²: Robot purchase didn’t work, due to bugs in the debugging code I inserted to try to deal with SRTY trades.  By the time I bought manually, it was ½ hour later and prices had conveniently fallen.  Unfortunately, I bought twice as much as intended because the tranche-size was still set to 20% of account, even though I have started using 10% tranches recently.
