Issue with color backgrounding executed and closed trades

Question

I have two issues with color backgrounding executed and closed trades :

I would like to highlight with a background color win and loss trades :

longExists          =  strategy.position_size > 1
// --- Check if trade is won or lost
isProfitable = strategy.netprofit > 0
// --- Background colors according to outcome
profitColor = color.new(color.green, 5)
lossColor   = color.new(color.red, 5)

bgcolor(longExists ? isProfitable ? profitColor : lossColor : na)

Background is set, but : 1a. one trade which should be backgrounded green (won) is backgrounded red and the trade is indeed won. 1b. one trade which should be backgrounded red(lost) is backgrounded green and the trade is indeed lost. Would appreciate your expertise 2. Transparency isn't working obviously

Would appreciate your expertise. Thanks.

Answer 1

Your script checks strategy.netprofit, which represents the total profit of the strategy and is updated at the close of each trade.

If you want to background color based on the PnL of currently opened trades only, you can check strategy.openprofit instead:

bool longExists =  strategy.position_size > 0
bool isProfitable = strategy.openprofit > 0

profitColor = color.new(#4caf4f, 5)
lossColor   = color.new(color.red, 5)

bgcolor(longExists ? isProfitable ? profitColor : lossColor : na)

The background will change dynamically, indicating on each bar of an open trade whether it was at a loss or a profit, until it is closed.
