Direct answer
The safest fix for the Boolean na problem is to stop asking the condition to be both a value and a truth state at the same time. Make the value explicit, then derive the boolean from that value.
This is one of those migration errors that is annoying at first and helpful later. v6 is forcing a separation that usually makes the script easier to read and maintain once the cleanup is done properly.
Where people usually get this wrong
Most failed fixes are too small. They suppress the error without clarifying the logic.
- patching one line without reviewing the surrounding state flow
- replacing na carelessly and changing the intended behavior
- hiding the problem behind nested ternaries and making the script harder to read
- assuming the script is fully migrated because the compiler stopped complaining
Copyable example
This is the kind of base pattern I prefer to start from before adding more filters, styling, or automation layers.
//@version=6
indicator("Boolean migration fix", overlay = false)
float signalPrice = ta.crossover(ta.ema(close, 20), ta.ema(close, 50)) ? close : na
bool hasSignal = not na(signalPrice)
plot(signalPrice, "Signal price", color.new(color.teal, 0), 2, plot.style_linebr)
bgcolor(hasSignal ? color.new(color.green, 88) : na)How I would handle it in a real build
I treat the error as a clue about unclear state. Once the script makes a clean distinction between values and conditions, the rest of the migration usually becomes easier too.
If your current script or workflow already exists and the behavior is drifting, send the setup or code on WhatsApp. I can usually tell quickly whether it needs a rewrite, a migration pass, or a smaller audit.

Frequently asked questions
Should I optimize this for backtests first or live behavior first?
Live behavior comes first. A cleaner live model usually gives you a more believable backtest, while the reverse is not always true.
Is Pine Script v6 the safer default for new examples now?
Yes. Traders still search with older wording, but new examples are usually easier to maintain and explain in v6.
When is the next step a service page instead of another tutorial?
Once you know the logic you want and the remaining problem is implementation, audit, or broker-ready structure, the service path is usually the better next move.
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.
