PineScript strange behaviour creating Table. Table is displayed as dot when using IF barstate.islast to create table.cells

Question

Hello I isolated code which cause this strange behavior. It is caused by variable price. Is there way around?

//@version=5
strategy("My script",overlay=true)


testTable = table.new(position = position.top_right, columns = 2, rows = 1, border_width = 1,border_color = color.white,frame_width = 1,frame_color = color.white)
if barstate.islast
    table.cell(table_id = testTable, column = 0, row = 0, text = "Text 1",text_size = size.large,text_color = color.white)
    table.cell(table_id = testTable, column = 1, row = 0, text = "Text 2",text_size = size.large,text_color = color.white)





price  = request.security(syminfo.tickerid,"D", high[1], lookahead=barmerge.lookahead_on)
crossover = (close > price)
strategy.entry("enter long", strategy.long, 1, when = crossover)

Answer 1

It is caused by barstate.islast. You creating table cells inside this local block. When cells are not created, with just table variable initialized with table.new() function there will be only a dot drawing (table borders without spacing between).

So barstate.islast is true for non ticking symbols, or after current last bar is closed (strategy calculates at close of each bar) for RT bars.

Use any other barstates, depending of your situation. E.g. barstate.islastconfirmedhistory will draw cells when bar is last historical bars. The barstate.isrealtime will redraw cells at realtime.

//@version=5
strategy("My script",overlay=true)


testTable = table.new(position = position.top_right, columns = 2, rows = 1, border_width = 1,border_color = color.white,frame_width = 1,frame_color = color.white)
if barstate.islastconfirmedhistory or barstate.isrealtime
    table.cell(table_id = testTable, column = 0, row = 0, text = "Text 1",text_size = size.large,text_color = color.white)
    table.cell(table_id = testTable, column = 1, row = 0, text = "Text 2",text_size = size.large,text_color = color.white)


price  = request.security(syminfo.tickerid,"D", high[1], lookahead=barmerge.lookahead_on)

crossover = (close > price)

strategy.entry("enter long", strategy.long, 1, when = crossover)
