# MSB

The default mode in REx. Built for intraday traders who want to be first in — before the crowd confirms the move.

> <kbd><mark style="color:purple;">**MSB Mode**<mark style="color:purple;"></kbd> is a market structure method based on fast trend changes.\
> It is designed mainly for intraday traders and is identified after a break, using the most recent opposite high or low before the point of the break to define the first range point.

***

**What it means:** A potential reversal. The market has broken structure earlier, before it reaches the extreme swing, giving you a head start on a trend shift.

> MSB fires earlier than BOS. Same break, different counter — different range, different Order Block placement.

## OB Placement in MSB Mode

The counter point — the structural level that defines the boundary of the range — is the **most recent** swing high or low found between the break point and the previous range extreme.

<table data-header-hidden><thead><tr><th width="40"></th><th></th></tr></thead><tbody><tr><td><mark style="color:green;"><strong>→</strong></mark></td><td>The OB candle is the last opposite candle before that recent counter point.</td></tr><tr><td><mark style="color:green;"><strong>→</strong></mark></td><td>The zone is <strong>tighter</strong> and sits closer to the break — the counter is nearby, so the search window is narrow.</td></tr><tr><td><mark style="color:green;"><strong>→</strong></mark></td><td>Reacts faster. Best for intraday entries where precision matters more than context.</td></tr></tbody></table>

{% hint style="info" %}
Switching to [BOS](https://docs.rexden.ai/deep-learn/editor/structure-str/bos) moves the counter to the most extreme level — producing a wider zone further from the break.
