I'm afraid I have to pause this experiment for two weeks as I will be on holiday. Trading should resume on 13/10. I am beginning to suspect the reversal trades aren't worth taking and may decide to remove them from the system when I return.

I am glad that the system is slowly building up a "cushion" of theo vs real slippage as I think this cushion will be required at some point on a big news item.

Incidentally, anyone burgling my house will have the chance to meet a burly cat-sitter :)

This mirrors my own findings, except possibly on US big news days.

Have a good holiday !

Quick update - started trading again today after a delightful sojourn in Patmos (the odd petrifying ferry crossing excepted) and noticed, with a somewhat oxymoronic mixture of emotions, that I would have lost around 62.5 pips had I traded during my absence.

Weekly updates from now on to save valuable thread space.

NB: Reversal trades have been eliminated from the system. This decision may be connected with a mild holiday epiphany experienced after reading "Fooled by Randomess".

Viva 7-9 BO:)

This is real world trading. Sometimes I take a holiday or a week off and I'm not going to choose when to do this by looking at my past few trades and waiting till I've had a string of winners! So I'm not including the above in the below, and I wouldn't have done if they'd been winners either :)

Live trades -

14/9 S 1.2256 stop 1.2279 T -23.5/ -23.5 R 1 pip slippage
15/9 L 1.2242 stop 1.2211 T -31.5 / -31.5 R 1 pip slippage

21/9 L 1.2194 Cl 1.2331 T +135.5 / +136.5 R 0 pips slippage

Total theo/real 136/151 over 21 days (6.48/7.19 pips per day)
Round trips 28

Back on target for 5 pips a day again. All commission included as usual.

Well, the 7-9 system has performed very poorly over 30 days. From my observations, it seems the 7-9 range is a shade too tight, resulting in too many false signals and stop outs. e.g Yesterday it missed that lovely run down by going long practically on the day's high. Perhaps the backtests enjoyed a number of days when the 7-9 range was wider and more volatile?

So from now on I'll be shamelessly using Jonny T's 7-10 range, with a 30 pip fixed stop, in the hope that it will reject more noise and only leap on the the back of honest, profitable trends.

Good news is that slippage has been minimal so that we now have 23 pips of "credit" when compared to theoretical results. The payroll data on Friday may well cause a dip into this credit, and then some! We shall see...

Results, FWIW

Well Frugi, at least you've proved that you can stick to a system, and as you say, if for that reason, as well as gauging slippage, it was by no means a wasted exercise, and thanks for posting the results. Were you using 7 to 9 BST ? Or GMT ?

I would offer to do the same, except that the purpose of the original exercise was to check slippage and theoreticals, rather than to produce great results. The emphasis is now more on the latter, and the exit strategy has now been modified to allow me some flexibility in deciding that I "don't like the look of it", and to get out early, but still with the -70 final stop, and an early -35 pip stop. Therefore most days it's hard to compare the two, other than to compare actuals with how I would have done with the original unmodified system. I'll run it this way for 3 months, and if my intuitive judgements do not produce superior results, say 30% more pips, then I'll go back to the rigid unmodified original system, and save myself the headache of all the extra screen time.

As an aside, looking back over past results, it's strange how the winning and losing streaks appear in groups. Often a good period follows a terrible one and vice versa. The nature of the market itself obviously goes through cycles, maybe depending on whether the commercials are buffering/capping prices, or letting things go. Or maybe it's just down to statistics ? However I still think it odd how the groups of results appear. Also I think it strange that (in this system's case at least), whether the market is in a clearly defined trend doesn't seem to have much relation to good/bad streaks. Do you find a similar pattern ?
