02 The foundation
Working tools, clearly scoped.
Understand
Test before
committing
Set price conditions before using real capital.
Follow relevant
information
Keep the prices and symbols that matter in view.
Keep a consistent
record
Persist paper trades, imports, and account state locally, so your record stays yours.
03 The strategy layer
Make the rule visible.
Simple technical investing should be explainable: what is being measured, what triggers a decision, and what happened when the rule was applied.
v0.1.5 includes guided backtest forms and strategy-specific parameters. This chart is an illustration, not an application result. Backtests are simplified simulations.
