What is the Best Multi-monitor PC for Day Trading?

Recommended Posts

that's 6 GB

 

 

the 2 GB committed refers to what is used... probably due to a 32 bit app limitation.

 

 

 

ps. that's only 4 cores with multi-thread...that's why it shows up on the TM as 8 core. (4 are virtual cores)

 

Tams, look at the physical memory total. That is 2gb. Besides, 32-bit OS memory addressing limitations max out at 3.2gb not 2gb as far as I am aware. That's why before win 7/vista(i know there is 64-bit xp but it was never widely available) 32-bit xp systems often were speced with 3gb of memory. The reason I said 8 cores was that he mentions multi cpu xeons and I suspect if it is an old system, it isn't multi threaded(or hyper-) although that was just a guess.

the Task Manager screen capture shows 6 GB.

 

I do not have a XP machine anymore, can't double check how the system property looks like. IIRC, it should show more than 2 GB.

 

 

btw, 32 bit OS can access 4 GB,

but under Microsoft's legacy architecture design, only approx 3.5 is usable,

and only 2 GB is available to each app.

 

 

btw (2), Xeon is the first CPU with Intel's Hype-Threading technology.

you have eight cores and 2gb of memory? if that's your trading rig, why do you need 8 cores? if it's for charting, why only 2gb of memory? where did it come from? which xeons are they? what is the memory spec? etc etc etc etc......

 

Yeah, I don't know why it's showing 2gb ram. It actually has 4gb ram. I will look into this. I been having fairly good luck buying reburbished commerical computers. It came with 8 cores, actually 2x4 core xeons. Same appl config is over 1000 on used market.

It shows 2gb physical memory.(in both screenshots)

I know it's 4gb so when I said "address" my wording was off. I didn't realise it was a maximum of 2gb per application

Yes I realise this, I was speculating that it was an old xeon pre-ht and this is confirmed now by lylec305.

 

re: 64 bit XP

 

although it shares the name XP,

it is actually a totally different OS (internally) than the 32 bit brother.

 

hence the problems with drivers.

The question I'd always ask is if you got it for 150 and yet they are going for over 1000, why is that? I know there's a chance the 1000+ systems are being unscrupulously overpriced, however, the discrepency seems to be inordinate.

Whatever, this computer runs great. I'm sure there is better but for $150 bucks it does the job. I would recommend the dell precision product line. Buying reburb maybe less than building, mine was...

I read it again, you are right, it shows 2 GB physical. Stange.

 

Especially considering it's meant to have 4gb. My guess is a loose memory module. Download cpu-z (actual latest download link btw). Look at the memory tab. If it's ddr(/2) memory and it says single in "channels#" then you know either one module(if it's a 2x2gb config) is either incorrectly seated or is faulty. If you re-insert it you'll get your full 4gb and it will run in dual mode giving you extra memory bandwidth.

It's funny how things don't always appear as you may think. :helloooo: I would plain but I would be wasting my breath. Just accept the fact that there are bargains out there if you know what you are looking for. Now, if you read my comment carefully, :haha: You would notice I said "aapl with similar config goes for over 1k". You most likely don't know what aapl is. moving right along, buy your best deal at best buy or costo, i'm sure your mom has a membership card. Ask them for dual xeon and quad core.. :rofl:

A warning to anyone reading. Buy any computer on ebay for $150 for trading and you are taking a big risk. appl, dell or otherwise.(or even an appl for $1000+-we all miss things sometimes when we are actually trading lyle, so show some respect)

Computers are so cheap and powerful these days, there is really no need to penny pinch to compromise your trading activity.

 

I would not buy a used computer myself, not for trading, and not even for playing. The reason is very simple:

a "deeply discounted", most powerful dual CPU xeon of yesteryear is not nearly as powerful as a middle of the road computer of today.

 

If anybody wants to save some money on computers, the only place I would trust is Dell refurb. They often have "new" computers, either due to overstock, or corporate customer restocks. Make sure you buy current models and not end of line computers.

We all need to earn respect not demand it. Before critisizing, get all the facts straight. without all the facts. How can anyone say $150 computer is bad when you are on a thread with someone that has one with 8 core xeon. I never said I bought mine on ebay.

 

System displays 2gb ram is normal for win32 XP. As long as bios displays 4gb installed.

lyle, don't get all defensive. I never actually said a $150 computer by definition is bad. Our jobs as traders is to look at all possibilities. Just remember that while the people posting on this thread may have some experience here, others who read it may not. These people may not be so lucky if they get a refurb.

 

And as for your comment about respect, whether you like it or not everyone here is required to treat all other users with respect. You don't have to always agree with people. That's fine.

 

Thanks for sharing your experiences and opinions and your comments will be noted.

Checkout dell refurb website for commercial grade hardware at reasonable prices. Lookout for sales, they drop the price buy an additional 50%...

My experience with HP and Dell purchased at the consumer level last a few months pass the warrante. But I have an old HP kayak workstation i bought new with dual P3, 13 yrs a go that's still running. Maybe you had better luck than me. I will take a dell precision over a dell insperon anyday. Totally differant class but they come with similar configs.

    • I have a serious question. It’s a question I’m grateful that many lab partners will have many good answers.   -   What are the results when the fed transitions from being the ‘buyer of last resort’ of bonds to being the ‘only buyer’ of bonds? thx
    • Date : 2nd June 2020. FX Update – June 2 – Weaker USD. Trading Leveraged Products is risky AUDUSD, H1 The Dollar has remained soft, with risk sentiment in global markets holding up, albeit with a weakening grip. Wall Street finished with modest gains yesterday, while the USA500 is moderately in the negative, and while Asian and European markets have gained, they are up by only a limited extent. US President Trump is weighing military action and imposing curfews in cities across the country in an effort to quell rioting, while there are glass-half-full market narratives arguing that, with many assets having recouped to pre-pandemic levels, there may be less upside potential with most economies across the world not expected to fully recover until such time as there is a vaccine or cure for the coronavirus. Despite the flagging risk-on tone, the narrow trade-weighted USDIndex edged out a new low, at 97.74, which is the lowest level seen since March 16th. EURUSD has remained buoyant, and has breached yesterday’s 11-week high at 1.1155, to trade to 1.1178. USDJPY remained in a narrow range in the mid-to-upper reaches of the 107.00s, which has been the case for about two weeks now. Sterling has outperformed on Brexit-related news, with the London Times reporting that the UK government is expected to signal a compromise on fisheries and “level playing field” trade rules if the EU backs off from its “maximalist” demands on regulatory alignment and fishing access, according to unnamed sources. Cable printed a one-month peak at 1.2555, while EURGBP fell to an 18-day low at 0.8865. AUDUSD edged out a fresh four-month high, at 0.6844. The RBA did the expected and left monetary policy unchanged at its June review today, maintaining the cash rate at 0.25%, while signalling that “the accommodative approach will be maintained as long as it is required.” USDCAD printed a fresh trend low at 1.3507, the lowest seen since March 9th. The Canadian Dollar, like other oil-correlating currencies, remains supported by the ongoing buoyancy in oil prices, ahead of the rescheduled OPEC+ meeting this week, while USOil trades at $36.00 currently.

    • Date : 01st June 2020. Events to Look Out for This Week.Geopolitics are back in the picture giving the markets pause and adding another layer of uncertainty to a shaky global outlook. However other than US-China tension, next week the global data dockets are heavy and results are likely to underscore the cratering in global economies this quarter. The calendar includes the US Jobs Report and Monetary policy meeting from RBA, BOC and ECB.Monday – 01 June 2020 Caixin Manufacturing PMI (CNY, GMT 01:45) – The Caixin manufacturing PMI is expected to slightly improve to 49.6 from 49.4 in May. ISM Manufacturing PMI (USD, GMT 14:00) – The ISM index is expected to slip to 40.0 in May from 41.5 in April, compared to a recession-low of 34.5 in December of 2008. Tuesday – 02 June 2020   Interest Rate Decision & Statement (RBA, GMT 04:30) – The RBA meet and are unlikely to move rates below historic lows at 0.25%, as RBA Gov. Lowe is his recent statement repeated that negative interest rates extraordinarily unlikely. RBA will maintain its expansionary monetary policies until progress is made towards full employment and we are confident on inflation . Wednesday – 03 June 2020   Gross Domestic Product (AUD, GMT 01:30) – GDP is the economy’s most important figure. Q1’s GDP is expected to slow down at 0.3% q/q and 1.9% y/y. Unemployment data (EUR, GMT 07:55-09:00) – The German unemployment rate in May is expected to have increased to 6.2% from 5.8%, while unemployment change is expected to have declined to 194K from April’s 373K. Meanwhile, Eurozone’s April unemployment rate should rise to 7.7% from 7.4% last month. ADP Employment Change (USD, GMT 12:15) – Lasts month, ADP report revealed a -20,236k April drop that undershot the -19,520k private payroll decline by -716k. For May a -9,000k drop is seen, since nearly all measures of activity rose in May from a trough. ISM Non-Manufacturing PMI (USD, GMT 14:00) – The ISM-NMI index is expected to rise to 46.0 from 41.8 in April. Most producer sentiment reports should show May rebounds after huge April declines due to mandatory closures, on top of the demand hit initially associated with the pandemic, and the oil price plunge with the OPEC price war, as re-openings are underway in most states. The April drop in the ISM survey was much smaller than the declines seen in other measures, however, and this is why we expect a further drop in May for that measure. Interest Rate Decision and Monetary Policy Statement (CAD, GMT 14:00) – On April 15, the Bank held rates steady at 0.25%, matching widespread expectations. In the next policy statement, the BoC is expected to leave rates unchanged, the Bank of Canada Governor Poloz said is his last interview that negative rates are needed only in extreme conditions. Thursday – 04 June 2020   Interest Rate Decision, Monetary Policy Statement and Press Conference (EUR, GMT 11:45 & 12:30) – Given that Lagarde buried any hope of a “mild” recession, the stage seems set for an extension of the PEPP program in size and duration at next week’s council meeting with an end date next year giving the economy more time to recover and EU aid programs to come into effect. Given that the ECB is no longer putting much hope in a quick recovery it is already clear that with the current time frame until the end of December that would risk a sharp widening of spreads in the second half of the year, when there is also the risk of a second wave of Covid-19 infections. Jobless Claims (USD, GMT 12:30)– US initial jobless claims contracted last week by -323k to 2,123k in the week ended May 23 after tumbling -241k to 2,446k previously. Claims have been declining since surging to 6,867k in the March 27 week. Friday – 05 June 2020   Event of the Week – Non-Farm Payrolls (USD, GMT 12:30) – A -2,200k May nonfarm payroll drop is anticipated, following a -20,527 April collapse, and a -701k drop in March. The jobless rate should rise to 17.5% from 14.7% from April, versus 4.4% in March. Nearly all measures of activity rose in May from a trough just after the April BLS survey week, but the initial and continuing claims data suggest a weaker labor market in mid-May than mid-April. Average hourly earnings are assumed to fall -1.0% with a partial unwind of the April distortion from layoffs being concentrated in low-wage categories. This would translate to a drop in the y/y gain to 6.6% from 7.9%. Labour Market Data (CAD, GMT 12:30) – Canada employment plunged -1993.8k in April, nearly doubling the -1010.7k tumble in March to leave a massive and rapid reversal in the labour market as firms cut jobs as most of the economy ceased to function amid the stay at home orders the began around the middle of March. For May employment should revealed a 4,000k drop in jobs, doubling again last months number. B]Always trade with strict risk management.
