INSIDE THE GUIDE
Practical concepts and decision checks.
Define risk before entry
Know maximum loss, target, time stop and invalidation before submitting the order. Avoid discovering the risk during a fast move.
Match structure to thesis
Long premium, vertical spreads and neutral structures express different views and carry different execution and assignment risks.
Review the trade
Record the thesis, structure, fill, exit and deviation from plan so the process can improve independently of one outcome.
