Item pricing #8

gergelyszabo94 · 2019-05-07T13:47:45Z

Prices on items in inventories and trade offers.
Ideas:

Currency picking, keys as currency
Pick from price providers, csgobackpack, cs.money, loot.farm, etc.
Option to set your own prices.
Option to count sticker value - set a % that the sticker's price should be added.
Total inventory value
Total value of selected items

Might be needed to store the prices localy in a "proper" database instead of simply in chrome.storage.local https://developers.google.com/web/ilt/pwa/working-with-indexeddb

The price scraping script is about finished in terms of functionality.
I will probably change it up a bit later, but the functionality won't change much.

gergelyszabo94 · 2019-07-08T11:42:10Z

The Lambda function is set to run every night and update:
https://prices.csgotrader.app/latest.json
And archive that day's data in this path:
https://prices.csgotrader.app/YYYY/MM/DD/prices.json


        added new *.csgotrader.app endpoints #8

gergelyszabo94 · 2019-07-10T23:11:56Z

Added pricing provider info as enums - these will be used in the options menu.

        only update latest if received prices from all providers #8


        added exchange rates scraping #8

gergelyszabo94 · 2019-07-11T15:29:22Z

The latest exchange rates the extension will use are available at:
https://prices.csgotrader.app/exchange_rates.json
It auto-updates every 3 hours and also archives in this path format:
https://prices.csgotrader.app/YYYY/MM/DD/exchange_rates.json


        added new keys to local storage for pricing #8

It explains how the prices are calculated and served.

The average market prices from csgobackpack are not always reliable.
I might implement my own market price scrapping.
The architecture would look something like:

A master list of all marketable CS:GO items in S3 or DynamoDB. It can be easily extracted from the existing pricing info.
A lambda function that puts all the items in an SQS queue. Each item is it's own message.
A lambda function that is subscribed to the queue, makes the API call towards Steam to get the market info then stores the result in DynamoDB or S3.
The price scraper script modified to use this pricing data instead or in addition to current sources.

As usual, if there are throttling issues from Steam's side it could get much more complicated...

It needs SIH or navigating to at least to the 4th page to trigger the full inventory's loading.
I will work on #47 tonight to eliminate the need for SIH in inventories. (except the occasional mass listing which is still not planned to be implemented in the near future.


        pricing algorithm update #8

Comment to possible own market prices scraping implementation:
https://steamcommunity.com/market/pricehistory/?appid=730&market_hash_name=P250%20%7C%20Asiimov%20(Field-Tested)
With calls like this it's possible to extract more detailed information.
