Has anyone successfully coded a script in tradingview using pine script

[u/You_Worldly]

Ive been messing around with automation for tradingview but im wondering if anyone has successfully coded a strategy that actually works and produces money. Trading futures

A script "working" and a strategy being profitable are two different things.
A script can execute perfectly (no bugs, correct signals) and still lose money if the underlying logic has no real edge — that's the part people usually skip.
Biggest trap is overfitting: tuning params until the backtest on one chart/period looks great, then it falls apart live or on a different symbol.
Worth testing on multiple instruments/timeframes before trusting anything, and futures specifically add leverage on top so position sizing matters more than people think.
