Just getting started with Pine Script and coding in general. I found a couple open source scripts that was able to signal a buy when there is an engulfing bullish candle. Is there a way to code it so that there has to first be 3 bearish candles and then a bullish candle to signal the buy? Image 1 shows what I am wanting with 3 red candles then signal a buy. Image 2 shows that there was only 1 red candle and then there was a bullish candle that signaled a buy.

threeRed = close < open and close < open and close < open oneRed = close < open bullishEng = close > open and close > max(open, close) buySignal1 = oneRed and bullishEng and not threeRed buySignal3 = threeRed and bullishEng
How to update the selected item in the proper QLineEdit? 3 textboxes and filled by various sets of data. If I click some items in QListWidget, every time first QLineedit only updated. Instead of this, I want to update data to the corresponding QLineEdits. ( for Ex: if textbox1 is focused, then the selected item will update in textbox1. If textbox2 is focused, then the selected item will update in textbox2). But In My case, Every time textbox1 is only updated....

You are passing the same instance of same listbox again and agian to MyFile constructor, and connecting the listBox clicked signal again and again, but connecting the signal works for the first time only, so you need to disconnect if it is already connected, so first try to disconnect the signal if it is connected:
I am converting a code from AMIbroker to pinescript, just wanted to ask if the method used is correct here and does the same since pine does not have REF keyword in there programming coding manual so I have used nz here....
ANSWERAnswered 2021-Jun-09 at 10:11
AO in pine is equivalent to
Ref(AO, -1) in Amibroker
There is code for the built in Awesome Oscillator indicator available in pine under the "Open" menu and under "New default built-in script" in the script editor
I am new in pine scripting, so please excuse me if the question is easy or impossible.
Here is what I have in mind:
If possible, I want to write a pine script (in tradingview) such that for any GREEN candle (in time frame daily) computes two numbers:
number_1: the number of consecutive green candles after that.
number_2: the number of consecutive green candles before that.
Also for any GREEN candle, I want to write number_1 above it and I want to write number_2 below it.
Thanks in Advance for you help and comments....

how to resolve the Undeclared identifier 'i1' error in pine script....
ANSWERAnswered 2021-Jun-08 at 07:39
As the error said, you have to declare
i1, starting with @version3.
In version 3 we declare it with
na, but from version 4 we declare it with
0.0, then you can write your formula/code and assign it to the same variable with
:= (if you use
= to the same variable, you will get an error,
The variable is already defined...)
I have a TradingView indicator in Pine Script, which I use for my trading strategy, but it doesn't have alerts in its code, and as a result, I miss some trading opportunities.
This indicator is a simple moving average SMA of the previous n period's highs or lows.
The indicator tracks both curves (of the highs and the lows). The close of the bar defines which of the two gets plotted.
I want to add a BUY alert when the price crosses the red line and a SELL alert when the price crosses the green line, but I don't have any experience in Pine Script.
I am attaching below the indicator's code and the screenshots. I would appreciate any help in adding these alerts....

I have been working on a pine editor script that is supposed to place a long order when the prior candle closing price (and current price) is above "Lead Line 1" and "Lead Line 2" of the Ichimoku Cloud indicator, and a short order when the prior candle closing price (and current price) is below both of the lines. Additionally, when an order is placed a stop loss should be placed either 2x the ATR above (for short positions) or below (for long positions) the entry price. This is shown visually by a trailing line above and below the candles. The take profit should be 1.5x the difference between the stop loss and entry price.
As you will see from my screen shots the long and short entries seem to be taken anywhere, and I am not too sure that the stop loss and take profit functions are working correctly either.
This picture shows a long position being taken both within the cloud and under the cloud (both of which I do not want)
This picture shows a short position being taken above the cloud, which also should not happen.
Does anyone have a solution to this problem? I will attach my code, but I will greatly appreciate any help or advice you can give....
ANSWERAnswered 2021-Jun-07 at 20:31
Try to plot your Leadline with no offset. The plot and the actual data of those two lines can be confusing.

In the end I just like Bart and Mike said there was no such tool that could help in the process of creating a documentation simply.

You have line 4 with every argument used, you have to know the sides (left, top, right, bottom) for your square, everything else is for design.
Please I'm a rookie at pine scripting and I've been trying to combine the stoch and the AO but the AO bars don't seem to appear in the indicator and there isn't any error message to indicate that there's something wrong. I was expecting the final result to look kinda like the MACD where the histogram and the smooths are interwoven together....
ANSWERAnswered 2021-Jun-02 at 04:47
AO isn't bound to a fixed range. On different instruments it's going to show very different results, while stoch is a fixed range 0..100. I'm guessing your probably viewing a currency pair and as such the AO is very small values compared to stoch. If you switch to something like BINANCE:BTCUSDT you will see the AO now has comparatively large values and the stoch becomes flattened.
You can rescale the AO to a fixed range, but it isn't ideal. You can use methods such as the highest(AO, length) to lowest(AO, length) or do it like BB% and use the stdev of AO to set the range.
