What’s New
A brand-new Learn section
We rebuilt the entire Learn area from the ground up: clearer guides with interactive diagrams, a glossary and FAQ, and broker cost presets you can drop straight into your fee settings.
We rebuilt Learn from the ground up. The guides were rewritten to be clearer and more concrete, and many now include interactive diagrams — small, hands-on illustrations that show how 0DTE SPX options, the option chain, orders, and backtesting actually work, rather than only describing them.
Two new references round it out: a glossary that defines the terms you'll run into, and an FAQ that answers the questions that come up most often.
Getting your costs right makes your results realistic, so your fee settings gained broker presets, too. Pick a broker from the list and its typical per-contract option costs fill in automatically, ready for you to fine-tune before you save.
