Volatility is so great that trends are essentially meaningless, I don't think that they can be considered predictive...The only conclusion I can come to is that at this time $/BTC is essentially trendless.

What about on monthly scales?

Compared to the pattern in early August (and June), there have been disappointing rallies to the (red) resistance lines according to my eyeballs (click to expand), though it looks like we're in the fourth Elliott wave of this week's rally.

I like the new chart format.  Easy to see the important stuff.  THANKS!

The $9 resistance on 8 August became the support on 12th (falling diagonal) similar to the $5.3 line on 10 September and I hope today.

I have learned that eye is quite treacherous when it comes to actually quantifying things like trend probabilities and buy/sell signals from charts.

I don't deny it. And even when things go exactly as planned, the mind changes strategies in fear or irrational exuberance. It's good to have cold calculus and perhaps an automated trade strategy, or so I imagine. Smiley

I feel the eye and mind are better at seeing patterns out of the box. Sure you can develop more sophisticated software at an enormous expense, but our inherent pattern recognition is quite fast, cheap, and programmable, if not reliable. The human can simultaneously see numerous timescales and visualize a future. On the other hand, he is forgetful, undisciplined, and has a wonderful imagination for better and worse.

In this particular case, I perfectly predicted the bounce point above $6 on the 7th, the rise above $7, and the fall to $4.5. Somehow I failed to make the expected killing, but that's a different issue I am working on. The rise back up is following a similar pattern, but gets trapped under exactly one of each of the previous half dozen support lines from August (and Mt. Gox is reporting dubious events that may or may not be happening).

Let us assume that those chart snippits are actually telling the same story, how do you turn that into an actionable trade? By deriving price targets?

Well, there's the rub. I set orders that either don't get filled or were too conservative and I lose terribly chasing the price. But how do you manage that with your probabilities? Set 5% of your wealth where there is 50% probability?

I believe the greatest value of analysis (such as your own, thank you) is in establishing calm confidence. Thanks for the June 13 tip. I've been looking at a few, but I'll give it special note. Cheers!

I posted this earlier, (and just accidentally deleted the text rather than quoting) because I thought it was relevant to the time series theme. Wouldn't you agree this looks disturbingly familiar?

Hi chodpaba,

I like your work, though I don't understand that much about that, yet.
So far I have been looking for the standard price changes (high-low, avg) and the trading volume.

In another post I read a comment of yours like: "can't believe anyone is still using the order book."

Can you loose a few words about that? What exactly are these graphics based on? Any literature, wiki-pages or so:)Huh

Cheers,
Harm

The left and right antennae of the H-Box plot are the extrema, in this particular case that means the <2% and >98%. The box itself represents the percentile range you describe, as determined by testing.

2% just happened!  Tongue

Accidentally deleted text Huh OOPS -netrin

The point was the first week of August looks uncannily like the first week of September (give or take a day).

Apparently the support curve is demanding some respect.

That's a... unique... way of saying that the bottom just dropped out.

Ha! You picked up on that...
I'm glad it was intensional. I was worried I might offend. Smiley

Just to get it in my symmetrical skull, is it correct that each box represents the 25%, 50% and 75% 'chance' of each price for the daily low (orange) and high (blue) and the antennae represent not-gonna-happen <1% boundaries? In the above case the 75% low is also the opening price, so it's also 100% impossible for the low to be higher.

The new chart looks great, but I still think that your model is too rigid and will does not account for the emotional, herding forces that are behind the market. Chart patterns and ElliottWaves do a better job, in my humble p.o.v. Your model might work in 80% of the time when there is almost no movement in prices, but then it is completely wrong when prices move in either direction, smashing through your support / resistance levels, and then make people fall out of the bed when they see that :-)

IQR: $6.51-$7.74
Median range: $6.88-$7.61

My interpretation is that we opened near the lows for the day, $7.50 seems easy, and the high end of the IQR appears likely.

I love your work, but hate when your intuition is wrong. Wink Day's not over yet, I guess!

If $7.10 is broken there is not much to keep it from going to $7.80.

Someone made a bidwall at 6.66 and this is what made it go up.  It is satan's influence on the bitcoin.

Apparently, one of my updates got eaten... Here it is again.
For Monday.

IQR: $7.53-10.45
Median range: $7.88-$10.00

The amount of resistance we would have to move through from the day's 'open' suggest to me it is unlikely that anything over $9.10 would be achieved today, but I would not expect the low to be below $7.80... If a decisive move beyond either of these limits happens then lookout...

Lookout.

This is why we are using some more flexible charting tools to predict BTCUSD. Rather than predicting each days range, we predict overall trends and price targets.

It could be as flexible as you would like, if you want 2% bars I can show those too. Incidentally the lower 2% bar for today is $5.08... But there is still strong support at $6.30.

I know it is not a traditional method of presenting the forecast, but it suits my purposes, and is there for anyone else it suits as well.

Suits me just fine. Keeping it simple appeals to me more rather than wordy and lengthy explanations to justify one's own predictions.

This is why we are using some more flexible charting tools to predict BTCUSD. Rather than predicting each days range, we predict overall trends and price targets.

And people forget that's the point of charting.  Patterns, once formed, are *lagging* indicators of price.  They're good for confirming trends and forecasting where price *might* go *if* trends remain unbroken.

Some indicators give signals which have a high correlation to a trend reversing.

Chart reading is NOT a time machine.  It's a way to assign probability weights to higher, lower, or same prices over a time interval.

That said chodpaba's charts and forecasts creep me out.  They're eerily predictive.
