From 5550702620758cc0eaa5fb0dd0a3ae3b117ce6d1 Mon Sep 17 00:00:00 2001 From: GitHub Date: Tue, 9 Jun 2026 18:56:07 +0800 Subject: [PATCH] fix(strategies): unpack BIAS triple return value in bias_reversal MyTT.BIAS returns (BIAS6, BIAS12, BIAS24) but the strategy was assigning all three to a single variable, causing 'array with more than one element' ValueError when comparing to a scalar threshold.
