BlowFish

There are a couple of datbase products that are designed for sequential data....I am having a senior moment though and the names escape me.

Ninja & Multicharts both integrate well with IB. Both support VWAP SD's & PVP. The former through EasyLanguage (its pretty much fully compatible) The latter through NinjaScript. Ediit: Oh and Amibroker links directly to IB & Head2k did great work on the indicators (used the former two for Jerrys stuff not Ami)

Darth one of the fundemental decisions to be made is how are you going to store your data? Many people go with SQL, it is not optimal for storing financial time series however on the flip side if you choose something like MYSQL there is a whole bunch of 'stuff' to get your data into other 'things' (like matlab).

Not sure if this helps....the time scale is exchange time so it starts at 8.30 central where the vertical dashed line is. 10 minute bars.

I hope thats not on my account. I am just a punter here gently (well I hope gently...others seem far more gruff:)) saying.....well it dosen't matter seeing as it was just an opinion . Certainly did not want to cause offence!

Actually Uma was selling nothing that was the big difference. It was just a few 'sceptics' thought he might do in the future. Completely different. Here there appears to a product available now for a monthly lease. It seems in contravention of the forum rules whereas Uma was clearly not breaking any rules. Not my forum not my rules. <shrug> Much better to get things on track now rather than have to throw people out. Other great contributors have been asked to cease and desist for much less btw. The point remains if you build something on a propriatery engine whether its is NeoTicker or TickZoom you are limited by that core engine. It defeats many of the objectives of roll your own. I am a great believer of using code modules toolboxes and libraries but unless you have access to the source you could find yourself hamstrung. Incidentally Neoticker will probably do everything you require, of course knowing what you require is half the battle As yet no one has discussed that in anything but the vaguest of terms. Having said that I agree diverse skills are needed however if you don't have those skills really your only option is learn them (realistically I'd allow 5 years if you have aptitude) or simply use an off the shelf. Isn't smartquant open source? dunno never looked at it seriously. Neoticker will do more or less anything you can conceive (no affiliation). Actually the task is not difficult (if you have the skills) but it is far from trivial. Wane, To answer your questions no it makes no sense to do the things you mention unless you have the expertise to do so quickly and efficiently (and as well or better than has been done before). Actually I do, but don't have the desire too In a previous life I was a software engineer so these threads interest me, ahh nostalgia. Actually it makes no sense to roll your own unless if you have at least a vague idea what you want and how you might achieve it. To be honest for things to move beyond 'wouldn't it be cool' it needs someone to sit down, write a brief, and hammer out a suitable architecture. It's not hard but would be time consuming, hell I cant be bothered to trade more than a few hours a week nowadays. Anyway credit to you mate as it seems you have done that. Seems that there is a niche for a decent user friendly open source project, but sadly I can't see it coming from this.

If you follow through to filefront and download the .swf file it seems t be the correct one. Perhaps a mod could grab it and embed it into the thread rather than having it offsite?

If you follow through the threads they are discussed at some length (probablly in the SD section). There are also ELAs kicking around and I believe Sierra and Amibroker code too.

Hey TickZoom, I'm sure your contribution here is welcome but as your core engine ins proprietary and costs a monthly lease I'm pretty sure that promoting it here (unless you are a sponsor) is a no no. (I know you aren't explicitly promoting it but it seems to be mentioned every other paragraph ) More importantly doesn't building a 'roll your own' on a locked propitiatory engine kind of defeat the object some what? Again don't want to diminish your contribution but can't help feeling that you might have a secondary agenda that may or may not be appropriate here. It might be worth having a chat with James (Soultrader)

Thanks. As DB points out to attract the widest audience it might be good to cut and paste the definitions so they are early in the thread. Just trying to be helpful rather than a thorn in your side

PF? - Price Failure? I guess when you have been posting this stuff for years it is easy to forget that not everyone will be up to speed with terminology. It would be helpful with a new thread at a new venue to treat people as complete nubs and give a brief explanation of terms and concepts as they crop up. Mind you even with a well defined terms mis-understandings still crop up, thats a whole other story .

Jerry used to use Ensign (when he presented this stuff).

I have to second that strongly. Also by coding you introduce rigour into your definitions which on the whole is a pretty good thing. Personally I find the 'symmetries' and 'geometries' in the market remarkable. Anyway as for AB CD's a good place to look for them is in a corrective leg of a larger move. The entry can then be taken at the D point back in the direction of the larger trend. Not quite what is being presented here. There is a piece of trading software that has this as its main premise. Another consideration with this pattern (and many 'geometric' patterns) is that it gives a projection in price and time. Not a bad thing to be aware of.

Bill Schamp pretty much completely revealed the settings of his indicators and his methodology in the 'early days'. Mind you from memory its is essentially based on price action using an ergodic to categorise significant HH's and LL's.

As I said before I don't want to take this off topic beyond the initial warning but in answer to your questions. Yes & it's certainly worth considering.

Yeah MBT have a good rep right back to there stock days...just be aware as banks tend to work in 100k units small orders are matched differently. You either need other MBT customers as counter parties or enough same side mini lots to make a full unit of the currency to trade with an institutional counter party.

I don't want to derail this thread DB quite rightly likes to keep things on track here. In a nutshell yes with a couple of notable exceptions (MBT & IB since you ask, maybe 1 or 2 others)

I think you are probably confusing stop and limit as was mentioned. From Currenex "On the Currenex service, users can place Limit, At Best and Stop Loss orders exclusively with user-defined bank counterparties. ESP™ Limit Orders are filled automatically by the first counterparty bank to stream a price that matches the order." My bolding. A limit order is an order to buy or sell an instrument at a specific price. A buy limit order can only be executed at the limit price or lower, and a sell limit order can only be executed at the limit price or higher. When you place a market order, you can't control the price at which your order will be filled. Sorry to flog a dead horse but everyone should be crystal clear on order types.

The 60min chart reminded me of a question. Might I ask do you find VSA that useful on a 60 min chart? For example 9 times out of 10 the last hour of the pit session is the high vol bar of the day usually followed by the 1st (or sometimes 2nd if there is 10.00am news) bar of the day. It just seems like a 1 hour bars volume is very susceptible to time of day. It seems to me that there might be value in comparing the last hours volume not only with the previous hours but the previous couple of days last hour volume? I guess that takes things outside pure VSA howver Just seems one of the least useful bars from a VSA perspective (but great for context).

I know (or 'eknow') a couple of people that have rolled there own. One of the more impressive is (racks brain......) Dcraig over at that other forum. There are various toolboxes and open source bits that can be cobbled together (don't underestimate the cobblng however). Btw if you are interested in swarms check out BioComps Dakota I almost bought it to play with....really couldn't justify it though.

1.5 : 1 is ridiculous but then again so is 200:1 and upwards. I guess it is to prevent people blowing up in 1 trade. Actually if you don't have an 'edge' you are likely to do better on a single punt before probability erodes your capital. Another story.

One of the first things that I noticed with Taylors' work was that he seemed to have a firm grasp of price action or the 'tape' as he refers to it.

Thanks for your reply as it is a major release do you plan a closed beta or are you going from internal test straight to the public beta? That was what I was angling at Just curious.

Damn I've been rumbled :\ though currently prefer Lord of the Rings Online. I guess I should add something imformative (though I am afraid it is rather negative). Be a little wary of forex yeah it's hugely liquid but most retail 'traders' don't have access to that liquidity. 99/100 'brokers' are actually bookies they are your counter party. Also the volume information is not actual volume it is limit order book changes that are reported. It's decentralised and pretty unregulated. having said that I have traded spot FX both with a 'bookie' and with a proper broker. I am just suggesting there are a lot more things to consider with spot FX than a centralised well regulated market. There is lots more I could say on the subject but better you do your own due diligence. Sorry for the digression I think its important.....back to your normal programming.

It's usually a combination of both (or appears to be from my observations). For example a largish market order(s) will hit eat through or wipe out a couple of levels on the limit book this may trigger stops or have break out traders jump in. Other side traders see this and pull their limit orders as clearly there is a good chance they can get them filled at better prices. That's just one possible scenario of course.
