minimum lot size — is it me, or has fxpro stopped accepting 0.1 lot sizes? at least on gbpusd it wont let me trade less than 0.2

Thanks, i'll give it a shot, but shouldnt a memory access error bring out the usual crash report either from mt4 or windows? The thing that makes me wonder is that nothing happens, i just go back to the computer to find mt4 is no longer running.

Your expert is perfect! Thanks again.

Thank You! will be testing it shortly.

you'll need something more complicated than a trade duplicator as i am guessing he also wants to look for these elusive arbitrage opportunities

The #1 mt4 coder in my humble opinion is prof. 7bit , but can you afford him?

I've been running Build 226 on wine almost non stop for a year. Has anybody been able to get build 229 to run under wine? on my installation it complains about a debugger (int 3), because of the new packing and checksum checking and general ...

i am not running an antivirus -- other people are, and they're reporting problems (which again you can google) However i am willing to bet a sizable amount of money that the reason build 229 does not run under wine (at least not on one of mine, on a ...

i tried the same wine version (1.2) that was running 226 just fine yesterday. The check also trips some antivirus tools who think it's a trojan -- after all checking for debuggers is pretty sneaky behaviour. Google mt4 build 229 and see for ...

excellent work as usual, professor. Thanks for sharing. Do you think it will be hard for me to change it so that it can be used across differnt instruments such as non usd pair, futures and metals? I would guess that there are some interesting, ...

it indeed can be done and has already been done in a number of ways..

but dont take my word for it -- try theirs: url some more appropriate dbs for columnar tick data: url $$$ url opensource url $$$ and file formats: url
- pippero replied Nov 7, 2010
Where do you think a DB stores its data, all in RAM? No, it's on disk like a csv. A simple file and directory naming scheme will go a long way. Let me remind you that tick data is generally strictly sequential and immutable -- it's not like you need ...

by the way, if you ever want to do a version that uses R.dll directly (and thus passes arrays natively), I'd be happy to help in any way i can, vc++ or lazarus. it would be pretty awesome imho.
- pippero replied Oct 23, 2010
Oh well, i guess i could always try using the writetobinary/readBin mechanism for passing vectors too, but it seems like we all have more cpus than we need these days. you should look into the tcltk / tcltk2 packages for R ; they have some sort of ...

you are the usual genius... i was doing this with sockets so far, and i am sorry for all the double to char array conversions i forced my cpu to perform. Cant wait to test this, thanks.
- pippero replied Oct 16, 2010
Sure, as long as you dont plan on logging more than a few instruments for a few months.
- pippero replied Oct 16, 2010
relational databases are a poor choice for timeseries data, and doubly so for high frequency tick data. I am logging 100000+ ticks on EURUSD _alone_ _per_ _day_. If you're tracking 10 pairs you're looking at a million rows per day. I doubt you can ...
