Study Displaying Current Bid & Ask Linear Extended Left & Right

[Paul Allen]

Here is a study showing current bid and ask linearly extended left /right.

script line
{
input barsBack = 1000;
input data = close;
def c = if !IsNaN(data) and IsNaN(data[-1])
then data
else c[1];
plot line = if isNaN(data[-barsBack])
then c[-barsBack]
else Double.NaN;
}
input length = 1000;

def b = close(priceType = "BID");
def a = close(PriceType = "ASK");
plot bid_ = line(length, b);
plot ask_ = line(length, a);

input limit = 0.02;
def priceB = close(priceType = PriceType.BID);
def priceA = close(priceType = PriceType.ASK);
AddLabel(yes, Concat("Bid: ", priceB), Color.Red);
AddLabel(yes, Concat("Ask: ", priceA), Color.Green);
AddLabel(yes, Concat("Spread: ", priceA - priceB), if priceA - priceB > limit then Color.RED else Color.WHITE);
# End Code

Hey thanks for posting this code, I was able to use some of the code to help with something I needed in my own scripting.

Hi, is there a way to show the bid/ask on the right axis price scale on the daily chart? It would be helpful to see where the price is on the daily scale especially after and premarket hours without having to look at a intraday chart to see it. As a reference TC2000 has this helpful feature. Thanks

ToS charts do not have that option.
This thread has a workaround that you might be able to adapt.

Thank you, I tried the script but it doesn't display on the daily chart

You are right. The ToS platform does not allow for bid-ask intraday data to display on daily aggregations.

Found it:



script line
{
input barsBack = 1000;
input data = close;
def c = if !IsNaN(data) and IsNaN(data[-1])
then data
else c[1];
plot line = if isNaN(data[-barsBack])
then c[-barsBack]
else Double.NaN;
}
input length = 1000;

def b = close(priceType = "BID");
def a = close(PriceType = "ASK");
plot bid_ = line(length, b);
plot ask_ = line(length, a);

input limit = 0.02;
def priceB = close(priceType = PriceType.BID);
def priceA = close(priceType = PriceType.ASK);
AddLabel(yes, Concat("Bid: ", priceB), Color.Red);
AddLabel(yes, Concat("Ask: ", priceA), Color.Green);
AddLabel(yes, Concat("Spread: ", priceA - priceB), if priceA - priceB > limit then Color.RED else Color.WHITE);
# End Code

Thank you for this indicator, it truly helps to see clearly the prices. I'm loading it during after-hours, and for some reason it does not show bid/ask afterhours although prices do change. Do you know how to enable it?

This study only works during regular trading hours (RTH) because it relies on real-time bid and ask data. Stocks don’t have continuous quotes in extended hours, and since there are long gaps with no data, the script can’t plot lines because that information isn’t available.
