PINE LIBRARY
TPOLib
Library "TPOLib"
TPOLib — Classical Time Price Opportunity (TPO) primitives.
Provides tick/row conversion, POC/Value Area calculation, TPO letter encoding,
Initial Balance tracking, and profile shape classification.
Note: Function bodies for f_price_to_tick, f_tick_to_row, f_row_to_price,
f_calc_row_ticks, f_poc_from_vals, f_value_area, and f_find_key_sorted are
copied from TPOSmartMoneyLib/3 (immutable on TradingView). No extraction or
migration - legacy consumers unaffected.
Architecture: L0 (no library dependencies, uses ta.* and math.* primitives only)
