# Product Annoucements

A list of changelog / new releases / product updates

<details>

<summary>Oct 1, 2026: Select all / Clear all on widget coin pickers</summary>

Multi-coin widget pickers now include Select all and Clear all, so you can fill or empty a coin list in one click. That means Screeners, Spaghetti charts, RankMaps, and other multi-coin widgets can support thousands of tickers in the same view.

<summary>Sep 21, 2026: New Formulas added. Change and Change%</summary>

New Formulas are now available across all products/widgets. Use them the same way as RSI, SMA, and EMA: pick a length to compare the current value to that many periods back.

```
change = close[t]- close[t-N]
change% = (close[t]/close[t-N] - 1)*100
```

<summary>Sep 1, 2026: Clearer API error messages</summary>

Invalid API requests now return descriptive `INVALID_INPUT` errors instead of empty `422` responses. The error identifies the failed constraint, such as an unsupported coin/exchange combination, and includes links to the api documentation.

**Example:**\
`Invalid coin 'btc'. Not supported on exchange(s): hyperliquid_xyz, lighter_spot`

<details>

<summary>Aug 27, 2026: Huobi and and Bitmex support removed</summary>

Bitmex and Huobi data is no longer supported across Hyblock widgets, APIs, and TradingView chart indicators due to deprecation.

The following bitmex-specific indicators have also been permanently discontinued:

* Leaderboard ROE / Notional
* User Bot Ratio

Any existing dashboards, indicators, or API integrations that rely on bitmex or huobi data will no longer receive data or updates. We will maintain historical data.

If you experience any issues related to this change, please contact our support team.

<summary>Mar 4, 2026: Position Decay for the OI / Net Positions Heatmap</summary>

We already use **OI Delta** to estimate where positions are opened. The challenge is that we don’t know exactly when those positions are closed.

That’s where **Position Decay** comes in.

As positions get older, their weight on the heatmap is gradually reduced, reflecting the increasing likelihood that they’ve already been closed.

The result is a heatmap that puts greater emphasis on **more recent and potentially still-active positioning**.

Users can control the decay rate using the **Decay Factor** slider.

**Bonus:** Zoom in to see the underlying OI footprint in more detail.
