About this app

The pre-computer charting method implemented properly: boxes sized by percentage, ATR or a fixed amount, a new column only on an N-box reversal, and the two classic signals — a rising column exceeding the previous rising column, or a falling column undercutting the previous falling one — outlined where they occur. Reports the compression from daily bars to columns and makes the trade-off explicit: anything below the reversal threshold is discarded rather than smoothed, so choosing a box size is choosing which moves exist.
