Trading - Automation

//@version=6
// ============================================================================
//  Trading - Automation  (OWS Auto)
//
//  UT Bot logic identical to QuantNomad's v4 original, converted to Pine v6.
//  No dependencies, no other indicators, nothing to wire.
//
//  Inputs match the cousin's chart exactly: 1 / 10 / false.
//
//  Two alerts to create, both "Once Per Bar Close":
//    OWS BUY   -> entry
//    OWS SELL  -> exit
// ============================================================================
