kandi X-RAY | rr Summary

rr is a Java library typically used in Manufacturing, Utilities, Energy, Utilities applications. rr has build file available, it has a Permissive License and it has high support. However rr has 7 bugs and it has 1 vulnerabilities. You can download it from GitHub.

RR is a generator of syntax diagrams, also known as railroad diagrams. It is a self-contained tool with both a browser-based GUI and a batch mode. Besides generating diagrams from EBNF rules, RR also can perform some grammar transformation, e.g. factorization and elimination of direct recursion. To some extent this transforms BNF to EBNF, yielding more compact diagrams.

repeat values of a column based on a condition

Asked 2021-Jun-16 at 00:54

I have a data frame including three columns named 'Altitude', 'Distance', 'Slope'. The column of 'Slope' is calculated using the two first columns 'Altitude', 'Distance'. @ the first step the purpose was to calculate 'Slope' using a condition explained below: A condition function was deployed to start from the top column of the "Distance" variable and add up (sum) values until the summation of them is greater or equal to 10 (>=10). If this condition corrects then calculate the "Slope" using the given formula: Slope=Average(Altitude)/(sum(Distance)). The summation of the 'Distance' was counting from the first value of that to the index that the 'Distance' has stopped there). The following code is for the above explanation (By Tim Roberts):

How to resolve Custom Sort Runtime error 1004

The error implies that it can't find a range to work with. As we are working with a table, the .Columns(2) wont work.

This part hints that you have a table that your are trying to sort.

There's two approaches that I can think of now, to solve this:

1. Sort a regular range by custom list

We can remove the table by:

Click on the table
Go to design tab
Convert to Range

Then your originally code will work (Changed Key1:=.Columns(2)):

Whether you are using re or regex, you will have to fix your pattern, as it is catastrophic backtracking prone. Atomic groupings are not necessary here, you need optional groupings with obligatory patterns. Also, you need to fix your alternations that may start matching at the same location inside a string.

QUESTION

Question about Automating Long vs Short Orders

Asked 2021-Jun-08 at 00:28

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.

According to that error message, my_data->thread_id does not seem to have a value between 0 and NUM_THREADS - 1. It seems to have the value 1103437824. This is probably because my_data has become a dangling pointer, due to a race conditon.

my_data points into the t_d array in the main thread. However, the lifetime of that object ends as soon as the main thread calls pthread_exit. Therefore, after that happens, the other threads' my_data pointer becomes dangling, which means it no longer points to a valid object. Dereferencing such a pointer causes undefined behavior.

The best solution would probably be that the main thread calls pthread_join on all worker threads, before it returns from the function main or calls pthread_exit. That way, it is guaranteed that the lifetime of the main thread's t_d array exceeds the lifetime of the worker threads' my_data pointers, so that these pointers never become dangling.
