Advanced trails - ATR chandelier, widening, Parabolic SAR and Supertrend

Beyond the classic trail

Beyond the classic width and the step lock, the TRAIL group has four more ways to trail. Each one changes how the stop follows the price. The ladder's TRAIL row always says which one is in charge.

ATR chandelier

ATR times is a chandelier trail: the stop hangs this many average true ranges, on sixty-second candles, behind the best price since entry. It is wider when the stock is thrashing, and tighter when it is calm. Until enough candles exist, the classic width is used, and the log says so.

Widen and per

Widen percent and per percent make the trail change as the move extends. A positive widen gives a runner more room each time it moves another per percent. A negative widen tightens it, to lock in more. It never shrinks below a fifth of the width you set.

Parabolic SAR

SAR is a Parabolic SAR trail: an absolute price that starts loose, and tightens by itself the longer the move runs. AF start, AF step and AF max set where its acceleration starts, how fast it grows, and where it stops. SAR exit decides the flip: off, it is logged and the trail carries on; on, the position closes. It never reverses. With SAR exit off, a flip is only logged, and the width rules keep the trail going.

Supertrend

ST is a Supertrend trail: a band that ratchets towards price while the trend holds, and never moves away. If it flips against the position, the desk logs it and falls back to the width rules. It never opens the opposite side. It only ever ratchets towards the price, while the trend holds.
