pub fn extract_condition_id(instrument_id: &InstrumentId) -> Result<String>Expand description
Extracts the condition ID from an instrument symbol.
Polymarket instrument symbols follow the pattern {condition_id}-{token_id}.
The condition_id is a hex string (e.g. 0xabc123...) and the token_id is a
large decimal number. This extracts the condition_id by splitting at the last -.
