# Sequence Reset <4>

#

The [Sequence Reset `<4>`](https://www.onixs.biz/fix-dictionary/4.4/msgType_4_4.html) message is used in response to a [Resend Request `<2>`](https://www.onixs.biz/fix-dictionary/4.4/msgType_2_2.html) message when one or more messages must be skipped over for the following reasons:

- During normal resend processing, the sending application may choose not to send a message (e.g. an aged order).
- During normal resend processing, a number of administrative messages are skipped and not resent (such as [Heartbeat `<0>`](https://www.onixs.biz/fix-dictionary/4.4/msgType_0_0.html) and [Test Request `<1>`](https://www.onixs.biz/fix-dictionary/4.4/msgType_1_1.html)).

Gemini does not support Reset mode ([GapFillFlag `<123>`](https://www.onixs.biz/fix-dictionary/4.4/tagNum_123.html) not present or equal to `N`).
