Checklister with sample data. Days you kept your rules and days you broke them stay on the heatmap.
Most losses come not from not knowing the rule but from not keeping it. Checklister turns your trading rules into a checklist and asks, on every trade, whether you actually followed them.
Once entries pile up, a compliance rate appears. The discipline heatmap and stats show which item you break most often and how P&L differs between disciplined and undisciplined days. Some items are judged automatically from trade data, so not everything needs a manual tick.
