Why does this code run:
// @version=5indicator(title="MA 1D", shorttitle="MA 1D", overlay=true) //, timeframe = "60", timeframe_gaps = false )var Grp_MA = "Using Moving Average on \"close\" source"int MAlength = input.int(3, minval=1, title="MA Length", group=Grp_MA, inline=Grp_MA)bool _display_MAlines = input.bool(title = "Display MA 1D lines", defval = false, group=Grp_MA)float MALine = request.security(syminfo.tickerid, "1D", ta.sma(close, MAlength))plot(MALine, title="MA Line", color=color.rgb(0, 255, 0), linewidth=1, style=plot.style_line, display= _display_MAlines ? display.pane : display.none )but not this code?
// @version=5indicator(title="MA 1D", shorttitle="MA 1D", overlay=true) //, timeframe = "60", timeframe_gaps = false )get_parameters() => var Grp_MA = "Using Moving Average on \"close\" source" int MAlength = input.int(3, minval=1, title="MA Length", group=Grp_MA, inline=Grp_MA) bool _display_MAlines = input.bool(title = "Display MA 1D lines", defval = false, group=Grp_MA) [MAlength, _display_MAlines][MAlength, _display_MAlines] = get_parameters()float MALine = request.security(syminfo.tickerid, "1D", ta.sma(close, MAlength))plot(MALine, title="MA Line", color=color.rgb(0, 255, 0), linewidth=1, style=plot.style_line, display= _display_MAlines ? display.pane : display.none )Cannot call 'operator ?:' with argument 'expr0'='_display_MAlines'. An argument of 'simple bool' type was used but a 'const bool' is expected.
I can not find the way to fix the 'const bool'.I tried to used const at different places but it does not seem declared on PineScript,
I also tried different variants like using another bool after the input.bool or before the plot line,
