MT5 Awesome Oscillator: Built-in vs Example iCustom Color Buffer Mismatch (the Tie Case)
MetaTrader 5 has a fun little habit: two things that look like “the same indicator” can behave almost identically—until a rare edge case shows up and ruins your day. This post documents a very specific parity issue I hit while building a deterministic benchmark pipeline (MQL5 exporter → CPU/GPU parity): Awesome Oscillator (AO) matched perfectly on the main value buffer (b0) but occasionally diverged on the color buffer (b1) when comparing built-in AO vs the Examples/Awesome_Oscillator.mq5
