Zen Fire data feed in fast market

Quote from NetTecture:

No, sir, I have a separate computer for trading, separate internet, more powerfull than I bet yours ;) Chances are on my side.

There are KNOWN issues with Ninja - there are various ways to overload it. Some are simple, some are not so much. All are known and documented.

Examples:

* Put a T&S into real time mode. It normally refreshes only x times per second. Real time, it will redraw (SLOW) on every tick. Good normally, fast markets see you lag terribly. This is actually documented - just some people dont realize that when they turn T&S real time. Happened to me.
* Strategies or indicators doing a singficiant amount of maths AND set to repaint / recalculate on every tick. Normally they run pretty simple. This is also the case if only little happens in the strat / indicator - for example, I use per tick data only to move trailing stops. No big problem. But if you do a lot of maths there, then the amount of work goes up in fast markets.
* Reloading historical data under certain circumstances freezes the platform until it is loaded. Happened to me a couple of times. This is partially also the case if you open / reopen / change the timeframe on a new graph and that goes up the window with CPU usage calculating bars.

It all runs down on running more complex code than average and / or a higher number of symbols. Most issues are well documented and - at times - ackknowledged by the Ninja trader staff. Read the tremendous amounts of things getting better with Nt7 - memory consumption, speed in certain aspects.

If / as long as what you do is sensible, Ninja is actually not that bad. But especialyl for non-IT people and non-programmes it is sometimes not exactly that easy to know realize how easy it is to overload the whole system with certain easy things.

I particularly like the real time T&S redraw issue. Someone may just put their T&S into real time mode, see the warning and see all is ok. Next time the market goes bonkers, you LAG. I got a10 second lag spike once, including my strategy trailing stops and putting in orders too slow - with a nice loss. Once I turned that off, acutally, I have no lag issues to start with.

That said, the other comments are right. Stuff like background proceses, internet connection etc may use up resources. Turn of BitTorrent while you trade, or get a separate uplink ;) No anti virus please - WHILE you trade, you are not supposed to download anything, so you can turn off anti virus DURING TRADING. Or do as I do - use a separate computer, ONLY for trading. NOTHING else installed.

are you talking timer refresh under properties of the T&S? being set to false from true (default)?
 
Exactly. If that is FALSE, this is refreshed real time. Which means a complete window repaint on EVERY tick. That just eats CPU like nothing else - that alone made me freeze during spikes.
 
I assume that with all this talk about needing a more enhanced Ninja, everyone already has their edge and trading successfully.

If the answer is yes, then switch to X_trader for now.

Better concentrate on actual trading, Ninja + zen-fire or Ninja + IB works fine.

X is awesome for eXecutions.

X Study is paultry for charting and limited in their analytics, however, their canned studies provide some of the best most common choices. Stochastics, etc, just to name one.


Ninja is like the AAPL iPhone with their apps, its worth the camera / cell phone / micro computer just for using the apps, more so than just using it to text or watch movies.

Ninja has more apps than X.
eSignal, TS, Multicharts have equally more apps than Ninja

some of these softwares have rewritten and released their updates to take advantage of multi core machines, both dual and quad core machines, by simply reading their host default environment variables and activating the features accordingly.

faster processing really makes a significant difference when having a flood of charts with a flood of analytics that require realtime recharting and regraphing, other than that, its like using a sports car to deliver groceries, fast but over matched.
 
i have a new E5200 2.5GHz cpu with 3MB ram integrated Intel GMA 950 video
have NT running with one chart + 2 indicators, plus a couple of realtime utilities
and MetaTrader 4 with three charts, Task Manager CPU Usage is 0%
when first loading an NT tick chart the Usage spikes to about 40%
the os is XP Pro sp2

Usage for instance if i scroll this ET page pops to 14% however
i suggest you purchase a new computer, mine cost C$430 taxes included and
i would recommend you purchase a similar base machine
if NT7 becomes stable in 2010 i'd think about purchasing a new Intel i7 computer
with Win 7 - but not now
there may be some who like to update as soon as 'new' becomes available but
there'll be many NT users who will remain with v6.5 for a long time because it's
stable

the issues which Andromeda and others experience i believe is computer related
and not an NT issue, and would only be solved with an up-to-date computer



besides multicore support which has limited benefits NT7 should be 64bit

Thanks. Took me a minute to stop laughing on that one ;) I had NT crashing 3 times today for one of the people I train here to trade. Db corruption included. The machine was replaced, checks perfectly in the lab so far on all but memory, and memory errors are VERY unlikely (ECC memory, no error shown). Tests still go on.

You are wrong. I have the most powerful computer you can buy, and NT chokes in heavy volume times with more than a small handful of charts open. You wouldn't know that because you are only running one chart, so you never see these issues. It is a reasonable expectation that a piece of trading software should be able to handle at least 10 simultaneous charts with reasonable lookback periods without choking, under all market conditions. NT fails in that regard. So yeah, if you hardly have anything open it's fine... but otherwise, not so much.

Take a look at the performance improvements on that page for NT 7 - you don't get 10-20 times performance improvement unless the first piece of software is a complete piece of garbage. If they designed it right from the start, there is no way they'd be able to get that type of % performance increase. That's only possible when you build a piece of crap and then finally get around to designing the next version the way it should have been done. I am counting the days until the end of September.

Yes... my installation has the wonderful property of crashing one out of every 5 times I press the "reverse position" button. Also, I would be careful about upgrading to the .12 version from .11... I tried installing .12 and it caused a blue screen of death. Someone else reporting the same thing on .12 running market replay. The answer from tech support was "NT can't cause a system crash, so don't worry about it". Not very helpful... I went back to .11 immediately.

no success on 64bits

there are some that claim that it works,
too many have found otherwise
 
Here is my Ninja set up:

5 charts (0 delay on each),
T&S (real time)
DOM

I have some pretty intense indicators loaded on charts that analyze DOM (the event is triggered when ever anything changes within any bids or asks).

This is a few year old pc with 2gb ram, core 2 duo, XP Professional. Works perfect even in fast markets. I have another similar one as backup on dsl, also no issue when I performs tests.

CPU is constantly around 10% -15% due to DOM indicators.
