Translated nine days of SOP into instructions the agent actually runs. Two things worth passing on.
I designed a labelling convention. It was wrong.
My agent reads price levels I mark on charts. So I specified a schema — FIB_0.618, RB_VAH, CH_POC — so it could parse them reliably.
Then I labelled some levels the way I actually think: "0.618 - for longs", "TP1 POC of range - move SL to entry".
Mine were better. They carry the role — what to do at that level — not just what the level is. And the agent is an LLM. It reads natural language fine. I'd built a rigid schema to solve a parsing problem that doesn't exist.
New rule: write how you think. Only the role needs to be recognisable, because that's what decides what the agent does with it.
