Round numbers: why 1.1000 behaves differently from 1.1013

Price tends to react at levels ending in 00, and to a lesser degree at 50 and sometimes 20 or 80. This isn't mystical. Human traders and algorithms alike place orders at round figures: take-profits, stop-losses, option strikes, limit entries.
The result is that these levels carry more resting orders than their neighbors, and price behavior around them is distinct. A move into a round number often slows, stalls, or reverses. When it does break, the break can be quick since stop orders cluster just beyond.
For scalpers, this suggests something concrete. Taking profit exactly at the round figure may fill less often than taking it two or three pips earlier. Entries placed just beyond the level can catch the stop-run momentum.
There are limits. In a strong trend, round numbers get sliced through with barely a flicker, and plenty of trades have been ruined by assuming a level would hold.
Counting how often price reverses within five pips of a 00 level versus a random level gives a quick measure of how much the effect matters on a given pair.
Do round numbers matter more on USDJPY than on EURUSD, or is that just folklore?
