Let the models mark the structure they read on this move.

The maths
Range = high - low Retrace (up) = high - range x ratio Retrace (down) = low + range x ratio Past 100% = the same line, ratio above 1 Ratios = 0.236 0.382 0.500 0.618 0.786
Draw from the start of the move to its end. On an uptrend the levels sit under the high and mark where a pullback might hold. Anything past 100% is the move having reversed through where it began.
Worked example
A move from 1.0800 up to 1.0900 is a 100 pip range. The 61.8% retracement sits at 1.0838, and the 161.8% level carries on to 1.0738 if the move fully reverses.
Where do these numbers come from?
The Fibonacci sequence. 61.8% is the ratio between consecutive terms and 38.2% is its square. 50% is not a Fibonacci number at all and is there by convention.
Which retracement matters most?
38.2% and 61.8% are watched hardest, and traders often treat the area between them as one zone rather than two separate lines.
Do I draw from the wick or the body?
Pick one and stay with it. Wicks are the more common choice, because that is where price actually traded.
