SPI Update 2-Feb-09

SPI Update 2nd Feb 2009-

Another trade finally!  There have been a few triggers but no filled trades since end of November 2008.

3 short trades just completed, not exactly to plan but profitable in the end.

SPI ASX CFD Short 28/01/2009 3455 2/02/2009 3468 -13 Large Exit Slip
SPI ASX CFD Short 29/01/2009 3530 2/02/2009 3468 62 Large Exit Slip
SPI ASX CFD Short 30/01/2009 3501 30/01/2009 3502 -1 Order error

Total Points = +48

Order 1 & 2 were exited today at open, but I didn't check the ASX CFD open price and had HUGE slippage.  I really hate the way ASX CFD's are executed, you have to watch the open yourself otherwise the market makers hit your bid/ask irrespective of the actually underlying price.  I use IB as my broker so I think I should have pegged the exit price to the SPI reall value & exited at market. 

Still, the overall trade was in profit, just could have been better.

Order 3 on Friday was an order error, I made a mistake on the exit if-done order & left the same price as exit in so I entered & exited on 1 day for a 1 point loss instead of exiting today for a profit.

Even with the problems my win / loss is still positive which is good, I just need to improve execution.

Till the next trade....

SPI Trades Update 04/12/2008

Well, I have been busy this last month with work, been to Newcastle & back for work to visit a coal mine in the hunter valley with my job as a contract process engineer. Carbon Credits and coal bed methane are part of the new environmental rage these days in Australia.

Update for last month is attached. Have to say one trade was a slight disaster & another sub-system has bit the dust, once again I relied on too few trades to accept the system & suffered for it. I actually hit a system stop at about 300 points & exited early, if I had not, I would have had double the loss.

I have to take back what I said in beginning about not having a stop, I don’t have a set stop per say, I use limit orders with a target which adjusts for various reasons to exit including an assessment of whether the price action indicates the trade is wrong. Sometimes this means the limit order gets me out next open. In addition I do have a disaster or system stop when evaluating the performance just in case the system fails (as in this case) - I look at the maximum expected drawdown from testing, if it approaches that, I check the system responsible & exit if required.

While the total return is still excellent, that drawdown is not! So I can admit a mistake, that system is in the bin. One bad trade really hurts the Win/Loss ratio. This also is what trading mean reversion can be like, a lot of good trades but an occasional outlier can bite.

One thing I have done is reduce risk even further, I now trade ASX SPI CFD for $1 Points while I am forward testing. These are not too bad but I do have to be at open once again as the ASX CFDs are a new market & liquidity is low, so limit orders at open do NOT work, the market maker just hits your order not the actual SPI open price.
