[U]Background:[/U]
For those of you that don’t know my personal trading style, which I think would be most as I tend to keep my own trading private, I focus on GBP/USD only. I have always used this pair and I have become acquainted with its various characteristics and ‘typical’ behavioural cycles. You’ll see in the title of this thread that I have mentioned EUR/USD also, this is simply since GU and EU are [in most instances] strongly correlated.
I have probably tested around five different trading approaches for GBP/USD over the past 6 to 8 years and I always experience an issue from September 2008 to February 2009. Now for those of you that are ‘on the ball’; you will know that this date refers to the financial crash. The daily range of both GU and EU exploded during this six-month period, with GU making 600+pip moves several times a week without even battering an eyelid. On the 24th October 2008 GU reached a daily range of around 950 pips – to put that into prospective, the average daily range of GU since 2005 to today’s date is about 160pips.
There was uncertainty and panic in the markets, this was clearly reflected as key price levels were not significant anymore and week after week new lows were being formed. Overall GU dropped around 7,500 pips, a 40% devaluation from its peak at £1.00/$2.11 [GBP/USD].
[U]Question:[/U]
Every system I test [regardless of them being able to adapt to the market or not] underperforms in the six-month period mentioned above. I am now curious to ask the experienced traders here who trade GU or EU and whom HAVE tested this six month time period if they have also experienced the same encounter. It really is a difficult time period to trade [U]if you are using a trading approach that works today.[/U]
For those of you that have the time, or perhaps already have the statistics from previous testing
“How well does your current trading system perform when tested from September 2008 to February 2009 - do you see a significant change in your ‘expected’ results"?
Remember, I’m only talking about a trading system that works now [or has worked after 2009] to be tested on the above six month ‘financial crash period’.
Hopefully the results, if any are offered, will make an interesting observation.
[U]Why is this relevant[/U]
If you’re trading successfully now and have a trading system with a positive expectancy which generates profit then clearly it’s time to think ahead. A market crash will happen again [at some point in the future], this is totally natural and part of the market cycle process. So by testing the most recent market crash you can at the very least provide a benchmark (or expectation) of how well your current trading system will cope - an approach that I always follow to ascertain the worst case scenario.
