[new tool]
               Bitcoin prices
                                  4 currencies
                                                    &
                                                       psychological levels nearby

Your opinion & suggestions please.

-->   btc.hopto.org   <--

  • When is the BTC price nearing a threshold? Many humans focus on
    whole numbers - 600 EUR, or 75000 JPY, or 5000 CNY or 750 USD.  
    So I coded a ...

  • ... new tool. It is live at  btc.HopTo.org

  • 10 exchange prices of some of the biggest BTC exchanges world-wide
  • nearby whole numbers - e.g. 700 750 USD, 4500 5000 CNY, 75000 80000 JPY, etc.
  • converted into USD EUR CNY JPY (via YahooFinance) - convenient for quick comparison

  • exchanges linked to bitcoinwisdom charts
  • exchange prices mutually compared, in percent -> arbitrage
  • new data every 1 minute, page auto-refreshes after 20 minutes

Please tell me what you think: --> http://btc.hopto.org <-- live, free, useful!  

Thanks!

Nice development... You might want to add something at the top of what the current level is holding at or can't break through and maybe the date of when the last break through was.

Nice development...
Thanks.

I thought it might be a good idea, to gather the data of the most important exchanges, all on one page. Plus, I have googled things like "683 USD in EUR" countless times - and now I don't have to anymore. And those psychological barriers are important, I have seen bull runs many times stopping just before, or after a number like 1000 or 5000, but then I never knew the equivalent in my currency. And I am checking bitcoinwisdom regularly so the links are being used - by me :-) I am using btc.hopto.org myself now, very often. My main user is myself, I guess. Because whatever I tweet, or reddit - I am getting almost no reactions.

So thank you very much for your post!  Please retweet/upvote/spread-the-word.

You might want to add something at the top of what the current level is holding at or can't break through and maybe the date of when the last break through was.

I am actually not sure how I would get that information. Please share your thoughts. Whatever can be written down in words sufficiently precise enough - I might be able to implement.

Do you mean when one of the exchanges passed one of those psychological barriers? Let me think about how to do that ... thx for the idea.

Everything is done on the fly, I am not keeping any data yet. If I start to store the results - I could perhaps show the past-24h-range somehow? Would that help?


Thanks!

Yeah, I was thinking like at the top you could say, "Next psychological barrier: 750USD - Date last broken - 12-09-2013".  You could sample where bitcoin is holding at from establishing an average over x amount of time and checking to see what the delta is between the next whole number.  If the delta doesn't shrink over time with respect to the whole number, it's likely you have a new barrier. You could then check to see when the last date the barrier was broken. I'm sure that wherever you are pulling the current exchange rate from, you can get the historical data too.  I believe bitcoincharts has all their data here, but you should check with them on fair use, etc. http://api.bitcoincharts.com/v1/csv/

Eventually, you could gamify this in some way...

Thanks for your ideas!

That is a good idea.

But which exchange to choose for that?
All exchanges & currencies are breaking their own psychological barriers rather independently.
In my first days with this, the range of prices was 12% (TWELVE!) apart. In the past days, that has shrunk to approx 5%.


- Date last broken - 12-09-2013".
My current concept does not need historical data whatsoever.

As soon as I jump through the hoops, and include historical data, all kinds of things would become possible. But it also needs time to implement it.
I have thought about your ideas - and decided against. Not my main focus right now.  

For me it's enough to have all that data available on one page - and let my brain do the remaining work  Wink


 You could sample where bitcoin is holding at from establishing an average over x amount of time
and checking to see what the delta is between the next whole number.  If the delta doesn't shrink
over time with respect to the whole number, it's likely you have a new barrier.
You could then check to see when the last date the barrier was broken.
You are describing a heuristics. An attempt at pinpointing that phenomenon. Would need quite a bit of trial and error, I guess.
Good idea - but not my main focus right now. Can you code yourself? Just give it a try, if you are interested in seeing how useful that automata might be for you. If you need help with that, I am happy to point you in directions, just ask.



I'm sure that wherever you are pulling the current exchange rate from,
you can get the historical data too.  
Nope. Not in any standard form at least. I am querying each exchange directly. And each exchange is different. Even to get only their price, needed one specific routine per exchange.


I believe bitcoincharts has all their data here, but you should check with them on fair use, etc. http://api.bitcoincharts.com/v1/csv/
That is a very nice resource, thanks a lot!

Eventually, you could gamify this in some way...
Not sure I understand.

new version 0.6

* bugfix: Currency rates were hardcoded rates from dev phase, stupid.
    Now real YahooFinance rates are used for conversion.
    The arbitrage spread looks more reasonable now, doesn't it?  Wink

* banner is pointing to "send me your offer" not auction anymore.

What else do you want me to implement?

Temporary f**kup

apologies, http://btc.hopto.org will be offline until repaired.


Yahho.Finance API is discontinued.

Thousands of projects & spreadsheets are broken.

Tens (or Hundreds) of thousands of working hours destroyed.

Hello Andreas,

Nice idea, too bad it is discontinued! My main question is: did it help you or someone else to better anticipate market movements?

What I completely agree on, is that there is a lot (say 90%) of mass-psychology going on in this market. Especially with the trading volumes I watch with www.pairtracker.com I see crazy things: sometimes volumes of a certain pair go up by 850% within three minutes! Often others are alerted as well, and a tokens daily volume can easily grow a hundredfold or more within a few hours - with predictable effect on price.

Am curious what your experiences are with your tool; Pairtracker is my project but I think we're trying to solve the same equation here ;-)

Best, René (NL)

Rene!

It is not.

Just on ice.

The googlefinance function I have already implemented, it needs a few more things to be changed, then it is good to go again.


My main question is: did it help you or someone else to better anticipate market movements?

First of all: Yes, I got a really nice donation once, so at least someone did appreciate it enough, and is or was using it.


And: Yes, especially while BTC was still moving slower (approx 1 year ago), those psychological levels were quite instructive. People did react to when the price had crossed them.

China played a larger role back then, and this tool helped me to realize when the Chinese markets came close to whole-number-levels.
I guess I should add a Korean exchange now.


Also, I often used it simply as a shortcut to quickly open bitcoinwisdom *g* (left side)

And the time table "Who is awake right now?" was sometimes also really useful (top right)

To get a feeling for the range of arbitrage between the different exchanges was useful too (bottom right)

the trading volumes I watch with www.pairtracker.com
I see crazy things: sometimes volumes of a certain pair go up by 850% within three minutes!
Often others are alerted as well, and a tokens daily volume can easily grow a hundredfold
or more within a few hours - with predictable effect on price.

That is a very cool tool you have built there.
I will keep it running, with 3min/5%/100BTC, for a while, to get a feeling for it.

First ideas:

* "update now" button (to skip waiting once)
* please let me fill in numbers with the keyboard, not only the arrow updown buttons
* http://www.pairtracker.com?t=3&p=5&v=100 to be able reopen with the same settings, without manual interaction
* also show the PRICE, somehow. Perhaps no need to keep it in every column cell, but perhaps the last price once, per row? I need to see the price.
* per cell I do not need absolute volume AND relative volume change. Perhaps put the absolute volume only once per row, and the relative volume change into each cell?
* (perhaps perhaps: per cell relative volume change AND relative price change?)
* colors not ternary (green red white), but as a range of (log?) volume proportional color intensity?
* poloniex? hitbtc? binance?
* sound alert above a given volume change percentage?

just some ideas. Perhaps you want to keep improving it?

If you have ideas and find the time, you can reciprocate:
http://btc.hopto.org/serve/TODO.txt
http://btc.hopto.org/serve/changelog.txt

I think we're trying to solve the same equation here ;-)
not 100% agree - those two projects are pretty different.

But I really like your tool.

Perhaps I'll add a page/link/popup/hover-div "other useful tools" - then yours will be there for sure.

Cool, I am an alumni too, however only of the short intro class, 2015.
Very much enjoyed that, learned a lot - esp. how much I already did know ;-)
Also really cool to have been a student of Andreas Antonopoulos.

Happy trading!
Andreas
