Storing price in a label?

[melfice_187]

Hoping someone can help me out with this. I'm trying to store the price(close) when the RSI crosses a certain value and store it as a label.
E.g., If RSI crosses the overbough line(70) get price and store it as a label.

AddLabel(yes, if RSI crosses below OverBought then AsDollars(close) else ????, Color.RED);

@magus You need to def a variable to store it first.

def p = if RSI crosses below OverBought then close else p[1];
AddLabel(yes, AsDollars(p), Color.RED);

Thank you @generic!

Is there any way to just store it once? This seems to keep updating as the price plays out. I would like to store it as soon as it crosses the overbought and hold that price level.

No, all variables must be updated for every bar/candle... The method is called using a "state" variable...

@magus one of the ways that I have seen for storing data and carrying it forward is with the barNumber() function.
Here is one example:

Is this somewhat of what you are trying to do?

Thank you @rad14733 and @MerryDay for the follow up responses. I'm coming from C# and javascript so sometimes my way of thinking doesn't translate to thinkscript.

in C# and Javascript there are things you can do to the system to trigger on events or run something on tick(update) only once.

Essentially what I'm trying to achieve is

• start checking price once RSI reaches above 70
• evaluate the last (x)bars since RSI went above 70
• check which RSI level was the highest and store it
• get a float price at highest RSI level
• evaluate current bar, if RSI is now lower than the highest point, stop checking and set the float price at highest RSI level

See if this helps.

This is brilliant, thank you @SleepyZ! I can't wait to play around with it more, my initial tests were good and its written in a way for me to play around with and learn more.
