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

发布于 2020-12-30 12:01:51

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)

Thanks, this should be worked. I encountered an another issue relating to this issue so if you don't mind I appreciate your help there too. stackoverflow.com/questions/65510011/…

Mamba is a new state space model architecture showing promising performance on information-dense data such as language modeling, where previous subquadratic models fall short of Transformers. It is based on the line of progress on structured state space models, with an efficient hardware-aware design and implementation in the spirit of FlashAttention.
