NRL line movement versus price movement
Distinguish a changed handicap from a changed payout before describing an NRL market move.
A price can move on the same line
Suppose Team A −4.5 goes from 1.90 to 1.85 at one bookmaker. The cover threshold stays at a five-point win, while the potential return falls. That is a price change on a fixed line, provided the fixture, market period and bookmaker are identical in both observations.
A line can move without the price changing
If the bookmaker instead changes Team A −4.5 at 1.90 to Team A −6.5 at 1.90, the return is the same for a win but a seven-point margin is now required to cover. These offers cannot be ranked within one exact-line comparison row. Record the line and price together at every observation time.
Describe observations, not reasons
The odds board can show current quotes, and a prospective record can show earlier ones. Neither automatically explains a move. Team lists, injuries, venue details and trading activity may all be relevant; use dated sources and say only what the observations establish.
Worked example
Illustration: a six-point Team A win covers −4.5 and fails to cover −6.5. Thus 1.90 at the newer −6.5 is not an equal-payout alternative to the earlier −4.5 quote, despite the same displayed decimal odds.
Illustrative numbers for explaining the calculation. They are not current bookmaker quotes.
Sources and method
All prices and results are hypothetical. A real movement report must use two saved observations of the same bookmaker and fixture; the live comparison page alone is a snapshot.
