Fibonacci SAR Pullback Limit

This diagram combines two Parabolic SAR speeds with a three-candle range, places one Fibonacci pullback limit at a time, cancels a resting limit when its setup reverses, and exits a filled position at range-derived levels saved with the entry.

Strategy Overview

Finished one-hour BTCUSDT candles feed fast and slow Parabolic SAR plus Highest(3) and Lowest(3). Decisions begin only after every indicator is formed.
The formed Lowest output releases one decision batch after the current Close, SAR, high, low, position, and pending-order state have all been captured.
A global pending lock permits only one live entry order. It clears when that order reaches its final state, while the sampled position prevents another entry after a fill.
Entry, cancellation, and exit predicates are evaluated from silent score latches and released once per finished candle, avoiding mixed values from adjacent candles.
The chart shows candles, both SAR series, range and saved protection levels, registered and cancelled limits, market exits, and all fills.

Entry and Exit Rules

Long entry: When Slow SAR < Fast SAR < Close, the position is flat, and no entry is pending, submit a Buy limit at Low3 + (High3 - Low3) * 50%. Cancel it if Slow SAR > Fast SAR or Fast SAR >= Close before it fills.
Short entry: When Slow SAR > Fast SAR > Close, the position is flat, and no entry is pending, submit a Sell limit at High3 - (High3 - Low3) * 50%. Cancel it if Slow SAR < Fast SAR or Fast SAR <= Close before it fills.
Exit: When an entry setup is accepted, save the side-specific levels. A long uses stop Low3 - 30 and target Low3 + (High3 - Low3) * 161%; a short uses stop High3 + 30 and target High3 - (High3 - Low3) * 161%. A finished Close reaching either saved level triggers one opposite market order of Volume 1.

Diagram Details

The Security Variable configures finished Candles; transaction blocks use Strategy Security and Strategy Portfolio.
Four formed-only Indicator blocks calculate both Parabolic SAR values and the separate three-candle high and low. The lowest-range output is the shared batch clock.
Formula, Variable, and Comparison blocks keep numeric inputs aligned, apply flat and pending-side guards, and emit only true action pulses.
Each accepted setup stores its calculated stop and target before its Order registering block is triggered. The saved values do not move while the position is open.
The registered Order reference is retained for addressed Order cancellation. The pending lock clears only from the registration block's Finished event after a fill, confirmed cancellation, or registration failure.
Side-guarded Modify position blocks submit a fixed one-unit opposite market order when the finished Close reaches a saved stop or target. The chart receives every relevant price, order, cancellation, and MyTrade stream.

Usage
