Dow 96 point entry

I totally agree with Jonnyt.

There is a significant difference between backtesting using the cash index and futures. The cash index really does flatter any system. Basically the futures move around a lot more than the cash and the futures data will also take account of the bid/ask spread. Obviously for spreadbetting you need to add a few more points in each direction to account for the increased spread that they offer.

Basically there will be times when you narrowly escape being stopped out on the cash index but which would be stopped on the futures. These will make a big difference to your overall results.

If you do want to use the cash to simulate SB prices then I suggest you allow 10 pts each way for testing. So if your long and your stop is 10400, count it as stopped out at 10400 if the cash price hits 10410. If your still profitable then, then your probably on to a winner!
 
The Daily Cash prices with a Spreadbet Company bear no relation to the actual cash index. The Spreadbet quotes move more than the cash index resulting in trades being stopped out or initiated when the y wouldn't have been with the cash Index

The SBs daily cash prices are more closely corralated with the underlying future than the cash index.

For this reason backtesting on non futures data is totally wrong.

I have developed many systems that work fantastically on the Daily Cash but actually lose in reality. You really do have to use futures data to stand any chance of getting results anywhere near the same ballpark in reality.

In case you havent heard:

YOU CANNOT TRADE THE DAILY CASH

I'm trying to be constructive here and give people the benefit of 3 years plus system development risking real money in real markets using both Spreadbets and Direct Access futures.

I have tested this system and it produced large losses for the December 03 contract. I hope all the followers out there can handle events that the backtesting suggests don't happen...

Again using the daily cash data I think the returns in reality will only be 25% of the expected at most. This alters the risk profile considerably.

Given opportunity I'll knock up a spreadsheet with futures data corresponding to this system.

Hi JT

Believe me I do appreciate the cautionary note you are waving and believe the system needs more work even though on the face of it it seems profitable as it stands.

I value your comments and do think that with any system you need others to look, comment and criticise. Hopefully, as we go through a few iterations of this process of development we will accommodate all views. It would be foolish of me to ignore a view which I respect in the development of the system.

I still see the system as an early beta. We have a concept which on the face of it looks to be profitable. If it can be developed further and proves itself to be robust then I will trade it. The instrument used for trading will be part of the development and I don't have a problem with developing based on cash but with a view to moving the work to futures once I am happy that we have a robust base system. I don't think it is an issue at this point of the development.

Looking forward to your continued input to this project.

Better but still not viable.

No account made for spreads and slippage. i.e. results are perfect entry and exit no costs.

I've been forward testing using CapitalSpreads demo account since 3/12/03, using £2/pt on the daily contracts (not DEC, MAR etc). Entries have (so far) always been filled at trigger price.

So far - 7 Buy triggers and 3 Sell triggers - P&L -£27.20p.

Intending to follow this system as it develops and keep testing.
 
This sytem seems quite good but sitting in front of the P.C every trading day seems a bit much, I would much rather trade a EOD style system which can run by itself with minimal effort. Much more appealing, anyway jpwone keep up the good work you'll get there eventually.

Nice thread tho mate, I like to see everyone coming together and talking like civilised adults, or am I dreaming.

Anyway I give you respect Jpwone

Regards

Mug,

I've just demonstrated that the system hasn't worked for at least 6 months!!!

JonnyT
 
hey JonnyT, it makes you just want to give up trying to be helpful and just post sarcastic comments instead doesn't it!!
 
When will people get it.

If it doesn't work with Direct Access then it sure aint going to work with Spreadbets.

Thanks for the support sidinuk, I only wish others would benefit from our market experience when it absolututely obvious they are naive beginners.

You try to be helpful and what do you get?

Maybe I should stop posting here.

JonnyT
 
Sorry only making a suggestion ,and no i was'nt being sarcastic
some people myself included make a very good living using SB .
No need to get out of your pram :cool:
 
JonnyT, I for one would miss your contributions if you didn't post. I'm sure there are plenty of people who have taken on board some of your comments over the years and have benefited from them.

The point is guys, experience comes at a cost both in terms of time and money. JonnyT is trying to save you both by imparting his own considerable experience. If you don't want to take it on board then fine, it'll cost you time and money to discover it for yourself.
 
Lol!

For once mr chill we seem to be signing from the same hymn book!
