Using the Asian range as a liquidity map for London

When Tokyo and Sydney trade, price builds a range that defines a clear high and a low. Stops from Asian session traders sit just beyond those extremes. When London opens, early movements often probe those levels, sometimes in a quick sweep that grabs liquidity before the real direction emerges.

For scalpers, the Asian range serves as a map. The high and the low become reference points, with higher probability of sharp reactions as price approaches them. A false break followed by a snap back inside the range is a recurring pattern, at least on certain pairs.

It is not a rule. Many days, price breaks and continues. The edge comes from conditioning: look at how the pair behaved on similar days, such as narrow versus wide Asian ranges, or after strong prior-day moves.

Record each morning whether London swept the high, the low, both, or neither, and what happened next. After a couple of months, the stats usually say something useful.

What fraction of London sessions sweep the Asian extreme before the real move on the pair being traded?
