问题 Symbol of the chart is being selected in another component with an update of state which is passed back as a prop to this TradingView component.

问题 It's probably really easy but I just can't figure out how to change the ticker symbol in the Tradingview widget. I want the chart to change to the tickers in a array i got. The chart needs to change every 30 seconds with a new ticker and do that forever. This is what I got so far: <div class="tradingview-widget-container"> <div id="tradingview_5889e"></div> <div class="tradingview-widget-copyright"><a href="https://www.tradingview.com/symbols/NYSE-RIG/" rel="noopener" target="_blank"><span

问题 I'm trying to re-implement the rma function from TradingView pinescript but I cannot make it output the same result as the original function. Here is the code I developed, the code is basically the ema function, but it differs greatly from the rma function plot result when charting: //@version=3 study(title = "test", overlay=true) rolling_moving_average(data, length) => alpha = 2 / (length + 1) sum = 0.0 for index = length to 0 if sum == 0.0 sum := data[index] else sum := alpha * data[index]

问题 This script will denote highs, with the left bar being lower and the right bar being lower. I also want this script to give me the HighofHighs, with the left high and right high being lower. I have it working but I can't get the label to display on the correct bar. If I use offset=-1, it will put it over the most recent high, if I use offset=-high_bars_back it doesn't offset it at all. (the default of the code is showing "HighofHighs" on the most current high (using offset=-1), but I need it

问题 When working on a pine script in TradingView (tradingview.com), I kept seeing red text appear near the top of the chart saying "out of depth at index" 540, and my script would not execute. Being new to pine script, I wasn't really sure what it meant. This issue was rather cryptic and difficult to google, so I'm posting the answer I found here. Hopefully it will be useful to someone. 回答1: I found an answer via this detailed writeup regarding the issue. Since stackoverflow doesn't like link-rot

问题 I have plot defined like this: plotshape(xvalue, location=location.absolute, style=shape.labeldown, color=red, size=size.tiny, text ="Upper") Problem here is with part text="Upper". I wanted to allow user to shorten label so it can be "Upper" or "U". This usualy can be done with something like this: text = label ? "U" : "Upper" Where "label" is true/false for shorter strings. Problem is PINE isn't accepting it and error is something like "You must use string literals with 'text='". https:/

问题 Hey I'm trying to save the close price at the time of strategy.entry to a variable so I can use it later for an exit. if condition strategy.entry("long", true) buyprice=close (strategy.exit("exit","long", when = close>buyprice*1.1) I get the error: Undeclared identifier 'buyprice' . From what I understand this means that the variable is not valid outside of the if statement. Is there a way to change this? Thanks in advance for your help 回答1: This is the only way that I could get this to work.
