I'm not at this time, watching casually. Thanks for your input and suggestion.

Wow, what's going on with NQ overnight? Getting pounded.

I hate to hijack your thread.. Yes, the ascending triangle is bullish, the media is bullish, everyone and their grandma is bullish. Here's one *shred* of evidence that this might be something of a top at least for tech. Bearish rising wedge. It's not the cleanest pattern, but watching that...

You are welcome. Just curious if you are still bearish on small caps in the short term. And, if so, do you have a stop loss level?

Cool. Are you sticking to your original plan (scale in to 94, stop 96, target 88) ?

I forgot to mention the real killers (these have most certainly burned me in the past when attempting to trade with similar amounts of funds in a futures account): - Overleveraging, particularly when in revenge or invincible mode. - Exceeding risk parameters related to stop placement (Let me...

I am not opposed to the idea, but all of the niceties and overhead that an RDBMS adds, such as ACID compliance, do not matter to me much.. so, processing gigs of data via SQL seems inefficient? I would imagine that one cannot compare flat serialized files to SQL, performance wise.

With $6k and 2% risk max, you have a max stop loss size of $120 and still have a decent (not large, but decent) risk of ruin, even assuming some type of positive expectancy. This doesn't even take into account the initial margin requirements of your chosen instrument. Taking into account...

Well, the above list is quite decent.. so at the least, if one were to pursue a genuine attempt at rolling-your-own in C++, it would be wise to at least try out/research the above options to gain insight. I am quite sure if I spent a ton of time without any point of references such as the...

You are a trader, right? What difference does it make where analysts are predicting the markets will be at the end of December? The market can do an immeasurable number of things between 5% and 12-15%. I might ask where do you consider your trade idea to be invalidated? Predictions are...

What are the statistics? With easy access to insane leverage via options, $500 margin futures, and 4:1 daytrading margin, retail traders have all the rope they need to hang themselves and render their edge, if they have one, irrelevant. One badly managed trade, regardless of your...

I had done this in C++ / Qt previously (believe it or not, using Qt's API for almost everything, forgoing STL and using Qt containers, serialization, etc.), but my skills as a software developer were vastly inferior to how they are now. Unless you're sketching up a quick throwaway idea, there...

I know OO, procedural, a *tad* of functional... but what exactly is 'vector-style' programming?

Looks like 90 is in fact touching *some* type of resistance... lol, kind of a broad stroke so maybe OP IS ON TO SOMETHING!! :)

Thanks SteveH, this merits further consideration. The advantage of using a familiar and 'general purpose' language like C++ or even C# is in the flexibility of what one can do to the data. I am not for sure what the Amibroker API provides or what limitations might be involved. Here's an...

To the OP, or others, Do you have a chart that details the price action of USDJPY dating back as far as possible? If OP is right and the very long term trend is in fact down (and is to continue down), maybe we could benefit from seeing if there is any long term resistance up ahead. I do...

Ok, I like the 'add to winner' idea instead of martinscaling. Just my opinion.

I think the other poster was simply trying to be of assistance, not necessarily to compete. I've been stalking the long USDJPY trade for over two years, and this does appear to be quite an impulsive move after a super long consolidation. Of course, it's nice to not be biased, so perhaps a...

All of the above. In my experience through various walks of life, the chosen tools do not matter much as an amazing maker can perform magic with just a hammer. Having said that, an artisan can certainly leverage the ideal tools.. so if using R to backtest, reimplementing in Java or C++ for a...

Curious if anyone has use haskell, erlang or possibly even ocaml for backtesting on tick data? I've wanted to learn one of these for quite a while, actually.
