thanks SC, Just reading through the onlydragon thread, what a psycho he is. FF has changed so much over the last few years, except this thread is still going strong :-) Mark

No worries mate, I know spotting the best setups takes lots of chart time and demo is a great place to get good without costing you anything. I agree with pinbar about fta being very important, when I was demoing it's as if I could almost see where ...

Hi Adilius, I disagree that you can only spot A trades (whatever that means) in hindsight. Setups that fit all your criteria should be able to be spotted just after a bar has finished otherwise you need to look at your method. One of the most ...

I'm sure this has been said many times, all the information is freely available in the free thread, you don't have to join the group. If you have any reasoning skills then you should realise this simple point destroys any of your sarcastic, ...

James16 is not credible

Comparing Jacko to James16 is silly, jacko offered virtually nothing for his fee as far as I can glean from his thread, and he scammed people. You are obviously a troll.

Hi folks, Merry Christmas and Happy New Year. Good to see the thread is still going strong, looking forward to 2011. I plan to get back into J16 after detouring into automated trading, which I have hit too many barriers at. I finally have a decent ...

James16 thread is still going strong, with some of the best posters to ever come to this forum frequenting it. I have joined J16 private forum a few times and the content there was well worth it. If you use the method and are serious then it's a ...

All the above are my current opinions, and I don't think you can't create good software with C++, you clearly can, I just prefer C.

When you need to grasp all these idioms etc then its a red flag that a language is poorly designed.

If it was only that then it would be ok, for me it tried to do to much as a language, I prefer a small simple lang that I can build on. Check out this comment by Linus Torvalds, I think he goes overboard but he makes some good points.

If you want to write truly efficient code your going to have to manage the memory, but its simply a case f using malloc and free along with valgrind.

Systematic trading

I would disagree, I tried out C++ and found it resulted in overly complex code, even for simple programs. I was only making use of strings and vectors, but you can easily write your own in C or use one of the many libraries out there. I found that I ...

Good point, This is not simply an exercise in seeing how fast I can load data. I wanted to have a base from which i could work from, I want to be able to run strategies over data, analyse over many stocks . The next step us to run validation over ...

Just an update on my HDF5 based data storage. I am doing all this in pure C using the hdf5 C api. I read a full 8 years of 1 minute ohlcv for a stock market symbol in 100 milliseconds or 0.01 second, from disk into a c array struct on the heap. Here ...

Sorry all I was saying is I think that the hdf5 performance is ok considering its reading from disk, as I say maybe with better hardware it could be fast enough.

Systematic trading

I see, but you are never going to get the same speed as reading from memory, I also dont know the bloggers hardware setup, so maybe it would have been improved greatly with a faster HD like SSD or velociraptor. Ill have a veliciraptor so will let ...

Im not sure what you mean, how does the data get into memory in the first place? How long does that take? You could do the same with hdf5 load the data up then iterate over it in memory.

I have only tested writing so far, I am implementing the strategy part, so I can actually use the data I have written on a strategy. However from the puppetmaster blog he was getting 1.28 million records per second, so I guess under 2 seconds for a ...

Does anyone know what happened to the blogger for puppermaster trading? He hasn't blogged since July!! Ive taken an offline copy btw, just in case his site suddenly disappears, there is so much useful info.
