Flash Magnet explained in a simple visual way

A flash magnet is a sudden liquidity jump near price. The level appears fast, is bigger than normal, grows sharply, and stays there just long enough to matter. Xtrend treats it like a fast reaction signal, not like a long-lasting wall.

How the Flash Magnet works

It is a short sequence, and all parts must agree.

1

A level appears near price

The liquidity must be inside the configured tick distance from current price.

2

It must be abnormally large

The size must beat both the minimum size and the average nearby depth baseline.

3

It must grow fast and persist

The queue must jump by enough size, then stay alive for the minimum persistence time.

4

It must react quickly

If it takes too long, it stops being a flash and expires.

How to read the Flash tag on the chart

The new indicator tag reads from left to right.

FLASH BID SZ 140 G60 T220ms
FLASH BID

This is a bid-side flash. A strong bid appeared below or near price and is acting like a fast support pull.

SZ 140

The visible size at the flash level is 140 contracts.

G60

The queue grew by 60 contracts versus its previous visible size.

T220ms

The flash has been alive for about 220 milliseconds since detection.

One-line customer explanation: FLASH BID SZ 140 G60 T220ms means a bid-side level suddenly jumped in size, is larger than normal, and is still alive inside the reaction window.

What each Flash parameter means

These are the settings that decide if a flash is weak noise or a real fast liquidity event.

UseBMFlashMagnet

Turn flash logic on or off

If off, the strategy ignores flash entries. If on, flash can participate in BM entry logic.

MinTicksFromPrice

How close the flash can be

Prevents counting liquidity that is sitting too close to price and not acting like a separate magnet level.

Lower = can catch very near levels Higher = ignores the nearest levels
MaxTicksFromPrice

How far the flash can be

Keeps the detector focused on nearby levels that can still affect the current move.

Lower = closer only Higher = wider search
MinSize

Absolute size floor

The queue must at least reach this size before it can be called a flash candidate.

Lower = more signals Higher = only bigger size
MinSizeIncrease

Sudden jump requirement

This is the extra size that must appear versus the previous visible size. It is the "flash" part.

Lower = smaller jump accepted Higher = bigger burst required
RelativeToAvgDepth

Bigger than normal

The queue must also be bigger than the recent average depth baseline by this multiplier.

Lower = easier versus average Higher = much bigger than normal
MinPersistenceMs

Must stay alive long enough

If it disappears too quickly, it is treated as noise and not a confirmed flash.

Lower = faster confirm Higher = must stay longer
MaxReactionMs

Still has to be fresh

If it stays too long, it stops being a fast magnet and expires instead of confirming.

Lower = very fresh only Higher = wider reaction window

Easy customer reading

If you want to explain it in one sentence, use this:

Fast support pull A sudden strong bid appears and attracts price or supports it.
Fast resistance pull A sudden strong ask appears and acts like a quick resistance magnet.
Short-life signal Flash is meant to react quickly. If it sits too long, it is no longer a real flash.
Important: flash magnet is a fast BM signal. It is not meant to behave like an iceberg or a long liquidity wall. It is a short reaction event, so speed and freshness matter more than long holding time.
