Arrgh! Don't remind me about 2011.
Apologies as I'm not posting results of a backtest. I'm happy sharing my real time performance for that time because I learned something very important.
I established my SMSF in June 07 and decided to manage it myself. As a complete newbie I handled the GFC like a champ. My market filter kept me safely out of the market and when the market recovered I pounced on the opportunities. I was into my fourth year of managing my SMSF and was feeling really good about my performance.
View attachment 101083 Then, 2011 started. This was the year of my max DD -17%.
I struggled to beat the market. I didn't stand aside like I did during the GFC but traded through it. What a dummy. From champ to chump. The DD happened in slow motion and I didn't see it happening.

My comment to the systematic traders and wannabe systematic traders is that you don't know how you're going to handle yourself in a larger draw down situation until you've traded through one and come out the other side.
Backtest draw downs are meaningless. They're just numbers. It's vital that you stick to your proven systems when you experience a draw down like we're all going through currently. The current fall in the market is putting us to the test. It's a good opportunity to see if we've got what it takes to be profitable traders.
@Skate 's post prompted me to see how my MAP Strategy fared during the 2011 down turn.
Below are the backtest results. As @peter2 rightly noted these are just numbers and mean nothing unless I am able to stick to my system. They, however, give me confidence to trade this system!
Backtest settings:
Portfolio: $30,000
Positions: 20
Commission: $6.60
Start Date: 1/7/2010
End Date: 30/6/2012

One of the indicators I put up on my Equity curve backtests is a count of weeks in DD. The depletion of "trading morale capital" will of course depend on how deep but also how long a DD lasts. Another tool for judging "would I really be able to keep trading consistently through such a period?".
I'm curious Skate - the PP strategy results you posted seem to have sailed through that period better than CAM and MAP, or am I mis-reading?
Thanks for sharing this project on "pocket pivots". I was interested in how you were going to code the pocket pivot (PP) The PP seems to be a better entry into a trend than the regular break-out of horizontal resistance.
The PPs are easily seen in hindsight but coding them was difficult. Some PPs are the same as a BO-HR bar, some are indicated by the CAM blue or green bars and others are marked by the MAP and P2 alerts. As mentioned, some of the PPs are the BO-HR bars while others appear in the first shallow price pull-back that tests the prior BO.
O'Neil knewThe PPs that provide the best RR form below the HR and "before the BO" (MAP, CAM-blue). Your Hybrid system with its triple setups probably finds a lot of PPs and this contributes to its overall success.
Hi @Skate, If you don't mind me asking, how did you deal with O'Neil's volume requirement used to define his "Pocket Pivot"?
Cheers,
Rob
Warr87, I see you provided MEGAN and Expectancy in your results. Skate has spoken on these before, but I have to confess I'm yet to "get it". Is MEGAN relevant to this currently thread direction about comparing backtest performance over historically difficult periods? Tried again today, but need more caffeine perhaps:

I suspect backtesting is a bit like strategies - there is obviously no one perfect metric that encapsulates all aspects of performance. Over a long period we gradually learn which backtest metrics provide insight into aspects of our strategy that were built in to match our goals and personality. I'm fairly sure there will always be something new to learn about Amibroker. My current level of knowledge leads me to emphasise these aspects in backtests I suppose:
1. What is the risk of going broke? (e.g. in a Monto Carlo run how often, hopefully never, does the strategy go broke, or exceed a max acceptable DD level)
2. What is the risk of losing faith (failing to continue following strategy signals) - %DD and length of DD typically very important here
3. What is average CAR over an extended period of poor and excellent momentum trading time periods?
(4. What is performance over GFC)
5. How smooth is equity curve, what is ratio of average profit/loss
?????
Incidentally, Amibroker is insanely helpful with backtest reports. Depending on your directory and backup structure, you probably have ever single backtest report you've even run if you do looking for the directly.
Looking at what I was doing in the first 6 months of owning Amibroker, I now just shake my head - wish I could go back and slap myself over the noggin.....
I think @Skate would be better explaining the importance of the MEGAN ratio.
I'm loving the conversations during this downturn. Been tramping in NZ and won't be back for a few weeks. Trying to keep informed when I have internet. Thanks to all contributors.
