Get value of Trend line like you do with SMA in PIne Script TradingView?

Question

I wanted to program algorithm using a trend line. It might not as simple as just crossover moving average, but as an example:

you can code crossover a SMA line like this:

crossover(close, sma(close, 50))

but how can I code crossover a trend line?

lineInstance = .. // define a trend line 
crossover(close, lineInstance)
crossover(close[1], lineInstance[1])

.. and more tricky algorithm using the trend line instance

Is this not possible, or do you have an idea? Thanks.

Are you using line.new function to define the lineInstance variable? If yes, you can use line.get_price(id, x) function to get the current y-value of the line object, and then pass it to crossover function.

currentLineValue = line.get_price(lineInstance, 0)
priceCrossUpLine = crossover(close, currentLineValue)
