1  Economy / Services / [Wanted] Developer for a short job, 0.15 BTC on: September 25, 2016, 10:31:37 PM
I need a web scraper tool. It should extract and download photos from the specific pages on booking.com (page URL provided as input for the scraper).

Input: list of URLs, each of them is a hotel page on booking.com (only one type of page)
Configurable: limit the number of photos to download.
Runtime: display the current status/progress.
Output: a directory for every hotel (named with the hotel's name) containing all photos from its page downloaded in full resolution
Platform: Linux (Ubuntu)

Example:
Input: http://www.booking.com/hotel/id/horison-seminyak.html
Output: directory 'Horison Seminyak Bali' is created, all hotel photos are downloaded to the directory in the maximum available resolution (so there would be 46 photos in the directory for this example).

It should allow me to configure the maximum number of photos to download per one hotel. For example if I set this limit to 15, it will finish scraping the hotel after 15 photos are downloaded and move on with the next one.

Language/frameworks are up to you, but it must be executable in Linux environment (Ubuntu).

I'll pay 0.15 BTC for this job.

PM me if you're interested.
2  Bitcoin / Project Development / [Prototype phase] Orderbook Dynamics Charts (useful for HFT/algo analysis) on: September 20, 2016, 07:42:02 AM
Hi everyone!

I've been developing trading charts that display orderbook dynamics, i.e. how orderbook changes with time. They help seeing how tens of orders are being created, removed and moved from price level to another, all that real-time. Below you can see some screencasts of that in action.

Features.
  • See the orderbook activity represented visually.
  • Watch bots activity, all HFT micro-events on a millisecond scale get charted.
  • Analyse algo-trading patterns of other players on the market.
  • Notice orderbook manipulation activity from bigger players.
  • Real-time

Examples.

Every line on the chart represents an order in the orderbook. Lines are colorized according to the order size.
Yellow to red lines are asks. Yellow ones are small. The redder the color, the bigger the ask size.
Blue to green are bids. Blue bids are small. The greener the color, the bigger the bid size.
White circles are actual trades.



Notice bots moving their orders in funny patterns:



Zooming in to a larger scale:



HFT activity, the bots are playing in the orderbook:



Contact me

Let me know if anyone is interested in the charts.

I'm accepting investments to speed up the development and provide the charts as a product. PM if you're interested in investing.


Cheers!

4  Economy / Services / Programmer looking for Bitcoin related job on: March 11, 2014, 03:20:07 PM
Hi all!

I'm looking for a Bitcoin related job.
So far I worked as a developer (mostly web) using PHP+MySQL, HTML+CSS and Javascript (including AJAX). Also had quite some experience developing scripts and bots on Python, and some experience with Node.js.
I have experience working with bitcoind as I've built an automatic gambling service (dice like), also did integrate Bitcoin payments to several e-shops using blockchain.info API.
I've got Linux administration skills as I've had to manage many VPSs and had Linux on my home computer for a while.

Bitcoin and cryptocurrencies are very interesting and progressive technologies, they inspire me to work in this direction. So I'm looking for opportunities to find my skills useful here. Smiley

I'm ready to be paid in BTC, LTC, NXT or whatever tradable coins you like.
5  Economy / Trading Discussion / Software for market manipulation? on: March 05, 2014, 03:37:46 PM
Hi guys!

There must be people who trade with big volumes here. I wonder, do you use any software to automate that?
For example, to move your "walls" in the orderbook quickly and carefully. To spread your buying/selling orders within a range of price. To buy/sell automatically at some level, but staying invisible for the orderbook until you do. Other stuff. Some of these things are even quite impossible to do without automation. Do you use something for that?
6  Economy / Trading Discussion / Instant trading instrument on: January 24, 2014, 11:14:47 AM
Hi all!

I'm developing a useful service for traders. So far it is an interface for BTC-e API. Features:
  • you buy/sell instantly, without typing prices and amounts
  • the trade is done at the current best market price
  • you trade with the whole available balance
  • you are sure the trade will be done right away, without any orders left in the orderbook
  • you see estimated effective price of your trade before you do it; it analyses the market depth, your balance and fee
  • all BTC-e pairs are available for trading

Check it out: http://instanttrader.org
There's a demo account to see what it is. You can register your own and use your API key. It has no access to withdrawing your money, API only allows trading.

Coming shortly:
  • market history and market depth
  • nice charts
  • more exchanges

I want to know your opinion on this. Can it be useful for you? What features would you like to see there? Which ones are the most important ones to implement?
