New Implementations and Upgrades

Desktop Specific updates

Changes for Coin List Page and Market Data:

Changes were made to the coin list, watchlist, and coin profile pages to provide more accurate real time OHLCV data. In addition, real-time data via websockets has been implemented for streaming value changes post page load. The last price displayed across the platform is a volume weighted average composite derived from data we aggregate from multiple supported exchange api’s. This methodology is also used to create a single set of historical values for our charting. More exchanges will be added on a continuous basis, which will expand our support for additional tickers.

When new price values are compiled on-the-fly, they are streamed in the currency list page, coin profile page, and your watchlist automatically. The new methodology calculates a weighted average of the OHLC across all exchanges using a 24-hour rolling window. Open, High, Low, and Close will be a volume-weighted average composite of the Open, High, Low, Close from each exchange. The volume will be a summation from all of the supported exchanges.

Currency Conversion:

Now users can select a conversion currency to set values sitewide to their preferred currency by choosing BTC, ETH, or USD from the dropdown menu on the coin page (more currencies to be added). When the preferred currency output is selected an fx conversion will be applied and new columns will be displayed. This fxRate is determined by creating a volume-weighted average composite OHLC.

All values are displayed in USD — $ in below screen as the user has selected USD from the drop down

Price by BTC

Price by ETH

The coins list can be sorted by clicking on the title of the columns. As an example a user can choose to sort the coins list page by volume, or supply in either ascending or descending order.

A new feature share coin has been added in our latest update. This feature enables a user to share their post on the timeline in relation to the chosen coin. Clicking share coin will automatically focus the post field and auto populate the cashtag symbol for that coin.

After clicking on ‘Share coin’ , will be prompted with a highlighted pop up where the user can share any comment on their timeline in relation to the selected coin.

Desktop Banner Advertisement

In today’s digital era, sponsors need space to promote their products with more efficiency and less manual intervention from the platform. For the ease of sponsors, desktop banner advertisement has been implemented with ability for sponsors to self-checkout when purchasing advertisements. This is a win-win feature for both the sponsor and investFeed team.

Sponsors can go to the advertisement page by clicking the ‘advertising’ button on the home page (before logging in).
