Windows update required as much computation as all scientific analysis through what year?

A recent Windows 10 Creators Update ran for roughly one hour on my desktop PC. The boot drive is an SSD and therefore I don’t think that much of the time was spent waiting for the hard drive. I don’t think that the update process per se requires much network access because the operating system told me that it had already downloaded the update. In any case, the computer is hard-wired to Verizon FiOS at 75 Mbps so there can’t have been too much network delay.

The CPU is an Intel CORE I7 5820K clocked at 3.3 Ghz. This machine has 6 cores. If we assume that an average of 3 of the cores were busy for the entire hour, that is equivalent to all of the scientific computation done through what year?

Instructions done in one second: 3 cores times 3.3 billion = roughly 10 billion instructions (the i7 is at roughly one instruction per cycle?). Instructions done in one hour: 36 trillion (3.6×10^13).

Good old days: The IBM 360/95 that was still kind of exciting when I worked on the Pioneer Venus project at NASA did 3.8 million instructions per second (Wikipedia). It would have taken 9.5 million seconds to run 36 trillion instructions on the IBM 360/95. That’s about 110 days continuously. So plainly by 1968 when the IBM 360/95 had been delivered to Goddard Space Flight Center there had already been more than 36 trillion instructions run.

How about the IBM 7090 workhouse circa 1960? Wikipedia says it could do 100,000 floating point operations per second. If the i7 can do floating point instructions at the same speed as other instructions (a big assumption? I’m not sure that Web page JavaScript is bound by FLOPS), it would take the room-sized mainframe roughly 10 years to execute 36 trillion instructions.

So I’m going to guess that my latest Windows update took roughly as much computation as the first 11 years of modern computing (start with EDSAC in 1949 and through 1960). Not all of that was done for scientific purposes, though, so maybe 1949-1962 is a better estimated period?

Readers: Corrections? Better ideas?

A Commanding Reversal and Target Update for AutoZone AZO

If you enjoy trading trend reversals and surprise bullish rallies (and breakouts), AutoZone (AZO) is the stock for you!

Here’s the V-Spike Reversal from Down to Up and the New Levels to Watch:

AutoZone (AZO) stalled with a Distribution Pattern near $ 725 with a breakdown (breakout) and Trend Reversal DOWN in April 2017.

From there, price collapsed from the $ 700 level toward the $ 500 Round Number pivot.

Rather than build a “Rounded Reversal” or Accumulation Pattern, buyers intervened to create a V-Spike Reversal that catapulted share prices through $ 600 and now $ 700.

We’re watching confluence target – now achieved – at the $ 700 price level.

Use this as your Bull/Bear pivot for short-term trading strategies.

Price initially stalled into the 38.2% Fibonacci Retracement just above $ 600 and when buyers took price above this pivot, a rapid rush of buying (and short-covering/short-squeeze) sent price speeding toward our current target.

Study this pattern to pinpoint similar/future reversal patterns like this event.

Quintet Update

Here I am on another plane, trying to squeeze a few ones and zeroes out of the pathetic GoGo “broadband” (more like a thin straw) to the Internet. But duties to Slope reign supreme, so I will make the best of it. I wanted to offer a view of my five options positions, by way of […]

Our August 15 Bouncing Emini Fibonacci Grid Update

With volatility back in the market (for now), let’s update our Fibonacci Grid for the @ES because – believe it or not – it’s STILL working very well for short-term traders.

Here’s today’s @ES Fibonacci Grid in play:

Emini @ES Intraday Trend Reversal

Monday gave us our strong, expected rally up away from the 2,440 critical pivot (that I’ve correctly been highlighting to members) and we now see price gapping up – and falling this morning – at our 2,470 Fibonacci Target.

In simplest terms for a quick update, our pivot points to watch today include (today’s gap-up high) at 2,469 and the 2,458 Fibonacci Levels.

A breakout above 2,470 suggests we’ll retest the high while a break under 2,458 means we’ll play lower toward 2,445 again.

Come join us to learn these tactics (beyond this simple/quick update) and have an evening game plan you can use effectively for the next trading day.

Quick Update

Just a quick update before I head out to dinner. The first trading day of the month generally leans strongly bullish, but as I mentioned on twitter last night, that’s not the case in August, closing green about 33% historically and with SPX closing down five of the last six. ES has been trading mainly […]

July 5 Emini Update Still Playing in that Lovely Fibonacci Grid

The market remained within the tight Fibonacci Grid we’ve held since June began.

Here’s today’s updated Emini (@ES) trading levels for your trades:

Believe it or not, we’re STILL within our short and intermediate term Fibonacci Grid.

The yellow “midpoint” highlight stretches from the 2,420 level to 2,432.

We’re BACK within the short-term range.

Note the powerful V-Spike Reversal off the 2,402 confluence – also at the 2,400 “Round Number” pivot.

We’ll continue using these levels until we get an actual – not one day – breakout from the magnetic pull of the grid.

Despite the fun Fourth of July holiday, that day was not yet today.

If you’re new to this style of simple level trading, welcome aboard and keep checking back or get more details beyond just the @ES (stock scans, money flow, education) by becoming a member!

Beautiful Color Structure Update of the Current Bull Market

As price (slightly) pulls back from the all-time high, let’s raise our perspective to the current price structure chart of the S&P 500.

Here’s our market from a different perspective:

Market Structure charts allow us to visualize the swings that build trends – in this case an uptrend.

From April to December 2016, price remained in a rising parallel trendline channel until price broke out impulsively higher in February 2017.

From there, structure “built” a narrower rising parallel trendline channel that takes us to the present moment.

We’re at the upper bound of the parallel trendline and our structure chart suggests a pullback from the high.

The logical target would be the lower rising trendline approaching 2,360 or – at a minimum – the midpoint near 2,400.

Sometimes simple approaches work best, and our “color structure” grid does allow that viewpoint.

Bullish Surge Forever June 1 Update

How dare we assume that this bull market will stop. How very dare we.

We were correct that a pullback was likely toward the 2,400 level, but now that it’s complete, it’s back on to new highs today and forever and ever.

Here’s your short-term Emini Fibonacci Retracement Grid and Target Levels:

The non-stop bull market hit a snag this morning, and we were planning for this as seen in last Friday’s “Planning a Pullback in the Emini.”

Price did retrace – for two sessions only – toward our 2,400/2,404 prior high and Fibonacci Target.

As noted last night, the positive divergences at our support target set the stage for today’s bullish surge.

Surge it did – the upside opening gap was the catalyst for another T3 Trend Day and buyers are delivering the goods (as short-sellers are being squeezed painfully out of bearish positions).

Our Pullback Plan is in Motion Emini Update May 31

We were planning a pullback and so far, the market is delivering right on schedule.

Here’s your short-term Emini Fibonacci Retracement Grid and Target Levels:

The non-stop bull market hit a snag this morning, and we were planning for this as seen in last Friday’s “Planning a Pullback in the Emini.”

Here it is – at least an initial pullback in price.

Note the short-term Fibonacci Levels which include the simple 2,400 overlap and then the 2,390 level beneath it.

Today gave us a steep drop from the high in an environment where the risk of a pullback is high.

Will the pullback to 2,400 be “all we get” in this raging bull market?  Follow along and trade accordingly.

Planning a Possible Pullback Emini Update May 26

I’d be a total fool for planning a pullback in this non-stop short-squeezed bull market, but humor me and let’s do it anyway just in case the market actually does pull back.

Here’s your short-term Emini Fibonacci Retracement Grid and Target Levels:

If you’re new to the trading world, you may either be puzzled by this endless bull market (“when will it end?!”) or overjoyed that you continue to make money easily and efficiently via buying every single dip this market gives us (“it’ll go up forever!”).

Still we’re trading the same market that does have a strong resiliency and persistent bullish strength.

Yes, Virginia there is a Santa Claus and Yes, Traders, the market will one day pull back.

Right now, your key focal points are the 2,415 “Bullish Ignore it All” above it (which continues the rally) and the 2,410 prior low level.

For a valid, objective plan, look to trade bearishly (intraday only) on a pullback “away from” 2,410 “toward” the first target of the overlap of the 23.6% level with the 2,400 “Round Number” target.

As traders, we are not forecasting but instead developing game plans for what we’ll do and how we’ll trade IF specific scenarios play out in real time.

Another Swift Surge to the Highs May 23 Update

Back to the highs we go again as this endless bull market simply continues after last week’s sharp dip.

Here’s today’s updated Emini (@ES) trading levels for your trades:

If you’re new to the trading world, you may either be puzzled by this endless bull market (“when will it end?!”) or overjoyed that you continue to make money easily and efficiently via buying every single dip this market gives us (“it’ll go up forever!”).

Still we’re trading the same market that does have a strong resiliency and underlying – persistent – bullish strength.

Here we go one more time above our Fibonacci Grid levels on a gap-up; price is traveling another bullish pathway toward the highs.

As intraday traders, we determine which side is in control for the day and go with that side – giving us another Trend Day so far.

As we approach the 2,400 target, increase your awareness/caution for another possible pullback from the target.

Up Up Up and UP Forever Emini Update May 22

Back to the highs we go as this endless bull market simply continues after last week’s sharp dip.

Here’s today’s updated Emini (@ES) trading levels for your trades:

If you’re new to the trading world, you may either be puzzled by this endless bull market (“when will it end?!”) or overjoyed that you continue to make money easily and efficiently via buying every single dip this market gives us (“it’ll go up forever!”).

Here we go one more time above our Fibonacci Grid levels on a gap-up; price is traveling another bullish pathway toward the highs.

As intraday traders, we determine which side is in control for the day and go with that side.

Right now it’s the bulls and with the exception of last week’s ONE DAY (can you believe it?) dip, buyers have remained dominant virtually every day.

Today – at least for the morning – is simply no exception to the bullish pressure and capitulation of the short-sellers.
