Reference for real time price.

[MTFtrendinator]

How do i reference real time price in think script.
I am setting up a conditional stop.
If at any time today the price drops below the "LOW" of yesterday, trigger a sell.

Not refering to todays "close" or "low" vs yesterdays low, but real time price to day vs yesterday's low.

thanks

Current price is referenced by Close which is Last trade price until the current Candle/Bar closes and then it becomes the true Close... And example would be "close crosses above ema9" as an immediate price comparison... After the Candle/Bar closes it becomes close[1]... It would then be referenced as "close[1] crosses above ema9" meaning the previous close... So for an active Candle/Bar, reference Close... Does this make sense for your needs...???
