四種放空資料，量的東西都不一樣：
- 空單餘額：某個結算日還沒回補的放空股數。FINRA 每月公布兩次，在結算日後約 8 個工作天。
- 每日放空量：每天在場外成交、申報給 FINRA 的放空股數。算的是成交，不是未平倉的部位；隔天公布。
- 交割失敗：到了交割日還沒交付的股數。SEC 每月公布兩次，晚約 2 週。
- 暗池（ATS）成交量：每週在另類交易系統與其他場外市場的成交量。FINRA 在那一週之後 2～4 週公布。

每日放空量
場外成交裡的放空量，不是空單餘額：每天申報給 FINRA 的場外成交中放空的股數，最近 30 個交易日。
放空量比例不能當成市場情緒：造市商為了接買單、避險本來就會放空，放空通常就佔場外成交量的一半上下。
