Enter a swing high and low and get the whole ICT Fibonacci set instantly — the 62–79% OTE zone, the 70.5% sweet spot, equilibrium, and the standard extension targets.
The highlighted band is the OTE zone. Equilibrium divides premium from discount — read premium and discount if that split is new to you.
Optimal Trade Entry is a retracement band, not a single line. The calculator gives you the whole set at once — the 62% edge where the zone opens, the 70.5% level most traders treat as the target price, the 79% deep edge past which the leg is probably failing, and equilibrium at 50% dividing premium from discount.
Standard Fibonacci trading leans on the shallow retracements. ICT leans on the deep ones, and the reasoning is about who is filling what. A shallow pullback fills very few resting orders. A retracement that reaches into the 62 to 79 band travels back through the bulk of the previous leg's inefficiency, which is where the unfilled orders actually sit.
The practical consequence is that entering at 50% usually means entering early, taking a worse position, and sitting through the rest of the retracement in drawdown. The band exists to stop you doing that.
This is the failure mode that costs people money with OTE. Price reaching the 70.5% level tells you where you are, not what to do. What turns a location into a trade is what else is present inside the zone:
An OTE level with none of those is just a number on a chart. An OTE level with two or three of them is the setup the model is describing.
The last three rows of the calculator are extensions rather than retracements. The −0.5 and −1.0 levels are the standard ICT targets once the entry works, and −2.0 is the full extension used on strong expansion days. They are measured beyond the end of the original leg, in the direction of the trade.
