Hi all,

I am slowly working my way through the 4 hour tunnel document that I downloaded and I have a query about the weekly chart and the results listed.

At the bottom of the table in the document it says that column 2 is the 'largest value for bull run". This can't be worked out in realtime. You don't know the largest value until several weeks after it has occurred. So I am not really sure of the point of the table in the document.

It also states that in the table "Any trades that looked like less than 100 pips in profit we totally ignored". What does this mean? Is this suggesting that we need to look at the profit potential of a trade before we take it?

Has anyone actually gone back through historical data and tested this strategy to see if it works? If you have, would you be willing to post the results? I am in the process of programming it into Wealth-Lab and will publish the results here when I am done.

Thanks

Simon

Column 2 relates to the value of "5 SMA – 21 EMA" the largest value for a for bull run/direction and "21 EMA – 5 SMA" for a bear run/direction. So it is not predictive.

I think it means they looked at the results of the trades and if the profit is less than 100 pips, they set the pip value of that trade to 0.

Back here http://www.forexfactory.com/forexfor...5009&post35009 I was looking at the 4 hr tunnel method. I programmed it into Amibroker. But no matter how I tried, I could never could 'mechanically' get anywhere near the results in the original document.

There was a little bit where there was discussion on the alignment of the 4 hr bars.

Some conclusions and results here with corrected results here

I would be very interested in seeing your results, although I might be a bit slow in confirming anything as I'm deep in backtesting another strategy.

I use AMIBROKER, would it be possible to see you backtest analyzer program? I looked at your results and you say the weekly is using the current week, But that is not known yet.

In your analysis have you selected, say something like this:

TimeFrameGetPrice( "Close", InWeekly, -1);

That would take the last completed week on and not the current one.

Thanks SMJ

I'm the techno-idiot I closed the screen before reading the the fact it was longer than 5000 chars. I've split it into 2 parts. You should see it in your PM now.

I also use Amibroker. I've been trying to back test the Vegas 4hr but haven't had much success due to my lack of knowledge of the code.

If you don't mind sharing your code with me I'd much appreciate it.

I've been using Amibroker for about 18 months now and AFL code still does my head in at times Just keep reading, testing and reading to get the hang of it.

yea, it is kind of like visual basic with arrays and elements of arrays. I have always wondered if the original model was Excel.
