Overnight data for 24/5 and 24/7 US equity Streams and tokenized equity Feeds now comes from multiple data providers. Replace the single-provider risk language with venue-concentration risk, since one venue still makes up the majority of overnight liquidity. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Looks good overall. Three small suggestions inline.
| - **Provider outage or disruption:** If the provider experiences downtime, technical failures, or connectivity disruption, the feed may flatline or report highly inaccurate figures, which can prevent users from reacting to real price movements. Such issues may lead to mispricing, failed liquidations, and potential bad debt accumulation. | ||
| - **Erroneous individual quotes:** Even when the provider is operational, it may publish a single bid or ask quote that is significantly off from the prevailing market price — for example, a bid price printing far below the previous in-session price. Because there is no second source to cross-validate against, this outlier quote directly distorts the mid-price calculation, creating a large artificial price move. | ||
| - **Venue outage or disruption:** If the dominant overnight venue experiences downtime, halts trading, or stops publishing quotes, the remaining venues may not carry enough liquidity to produce a representative price. The feed may flatline, update less frequently, or reflect thin quotes, which can prevent users from reacting to real price movements. Such issues may lead to mispricing, failed liquidations, and potential bad debt accumulation. | ||
| - **Erroneous individual quotes:** Because one venue makes up most of overnight liquidity, a bid or ask quote on that venue that is significantly off from the prevailing market price — for example, a bid price printing far below the previous in-session price — can still distort the mid-price calculation and create a large artificial price move, even when it is reported consistently by several providers. |

Splitting the sentence removes the opening "Because" and the em dashes:

| Overnight session price data is sourced from multiple data providers. However, far fewer venues trade during the overnight session than during regular and extended hours, and a single venue generally accounts for the majority of overnight liquidity. This makes the overnight session less reliable than regular and extended hours, which draw on a broad set of venues. | ||

| If providers experience downtime, technical failures, or connectivity disruption, the feed may flatline or report stale values. Such issues may lead to mispricing, failed liquidations, and potential bad debt accumulation. | ||
| Multiple providers protect against an outage at any one provider, but do not fully remove the dependency on the dominant overnight venue. If that venue experiences downtime, halts trading, or publishes erroneous quotes, the feed may flatline, report stale values, or reflect an inaccurate price. Such issues may lead to mispricing, failed liquidations, and potential bad debt accumulation. |

"Protect against" is only true if the overnight quorum survives a provider dropping out. Unless we've confirmed that config, I'd soften it (same change suggested on the 24/5 guide).
This also adds one sentence on overnight smoothing, since feeds now smooth the overnight session with an EMA. Wording reuses what's already published on the 24/7 page. Streams are unsmoothed, so this sentence is feeds-only.

Same softening as the feeds page: "protect against" only holds if the overnight quorum survives a provider dropping out.

Summary
Overnight session data for US equities is moving from a single data provider to multiple providers. One venue still accounts for the majority of overnight liquidity, so the risk is reframed as venue concentration rather than removed.
