A Pine Script indicator can look perfect on a chart and still fail live if the plotted signal, alert condition, timeframe request, and candle confirmation do not match.
When a trader says an indicator looks right but fails live, I do not assume the trader is wrong and I do not assume the code is broken. I recreate the exact path: what the chart showed, what the condition calculated, what the alert fired, and what happened after the candle closed.
My debugging sequence
I first separate visual plotting from signal logic. A plot can look correct while the alert condition is using a different series, a different timeframe, or an intrabar value. Then I add temporary debug plots so the script exposes its own decisions.
//@version=6
indicator("Signal debug overlay", overlay = true)
ema20 = ta.ema(close, 20)
ema50 = ta.ema(close, 50)
rawSignal = ta.crossover(ema20, ema50)
confirmedSignal = rawSignal and barstate.isconfirmed
plot(ema20, "EMA 20", color = color.teal)
plot(ema50, "EMA 50", color = color.orange)
plotshape(rawSignal, "Raw signal", shape.circle, location.belowbar, color = color.gray, text = "raw")
plotshape(confirmedSignal, "Confirmed signal", shape.triangleup, location.belowbar, color = color.lime, text = "ok")
alertcondition(confirmedSignal, "Confirmed buy", "Confirmed buy on {{ticker}} at {{close}}")Where the truth usually appears
- The raw signal appears intrabar but disappears before candle close.
- The MTF request uses a value that changes while the higher timeframe candle is open.
- The alert was created before the latest code was saved and re-added.
- The script uses visual labels but the alertcondition uses older logic.
- The trader is comparing replay behavior with live alert behavior without matching settings.
Why this matters for paid builds
A professional Pine Script developer should not hide behind pretty charts. If the signal fails live, the developer should be able to explain why. That is the standard I use for Jayadev Rana projects: visible assumptions, debug-friendly code, and alerts that match the actual trading decision.

Frequently asked questions
Can Jayadev review my existing script?
Yes. Send the current Pine Script, a chart screenshot, and what you expected it to do live.
Will the code be Pine Script v6?
For new TradingView work, I prefer Pine Script v6 unless the client has a strong reason to maintain an older version.
How fast can I get a quote?
For clear requirements, I can usually give a fixed-price quote within 24 hours.
Primary sources and references
I take on Pine Script indicators, TradingView automation layers, strategy audits, and broker-aware execution workflows when the goal is clear and the live behavior actually matters.
