Price level indicator


New member
I'm looking for an indicator that draws a horizontal line all the way across the screen at the current price level (and obviously adjusts with price). I think this comes standard on tradingview but doesn't on TOS for some reason. I got this script from someone else and it works fine, however, the problem is that you have to adjust the length, so on some time frames it's very short and on others it's very long. Does anyone have a script that would show a horizontal price line extending throughout the entire chart no matter what time frame is used? Here is the code I started with for reference:

#Plots a Horizontal Line that follows the price value selected
input price=close;
input offset=0;
input length = 300;

def sma = SimpleMovingAvg(price, 1, length);
rec line = if IsNaN(sma) then line[1] else sma[offset];
plot priceline=if isnan(sma) then line else double.nan;
@BobbyJJ22 There are several PriceLine indicators here in these forums, as well as elsewhere on the internet, that display all the way across the chart... However, due to recent changes made to Thinkscript they no longer work without lag... The culprit is the use of the HighestAll() function... It seems that the folks at TD-Ameritrade/Thinkscript limited the use of all functions that look at All candles on a given chart... I am fairly certain that this is due to the use of overly long lookback charts by some users that add unnecessary burden to the server farm... Due to the fact that these functions have been throttled back, only updating every several minutes like some Custom Watchlist Columns, alternate methods of displaying the PriceLine have been implemented... The code you have posted is just one example... In reality, do we really need to see the current price when we scroll the chart back days, weeks, or months when we have the current price displayed at the top of the chart...??? While a convenience, it surely isn't a necessity...
