An assistant for backtesting trading strategies and showing external signals in Tradingview

Description from store
Functionality
1. Backtesting trading strategies, optimisation of the strategy's parameters:
* automatic getting a list of parameters and their types (numeric, lists and checkboxes are supported)
* generation of the testing range according to the rule: the beginning value is 2 times less than the current one, the end is 2 times more than the current one.
* saving the generated parameters of testing a trading strategy for their correction as a template in a file in CSV format
* Loading adjusted parameter ranges from a CSV file
* Configuring the optimization model:
* Choosing the type of optimization: searching for the maximum or minimum values
* Selecting an optimized value from the entire list of strategy results in Tradingview (Net Profit, Ratio Avg Win / Avg Loss, Sharpe Ratio, Sortino Ratio, etc.)
* Choosing a search strategy in the parameter space(random, sequential, annealing method)
* Filtering of unsuitable results. For example, the number of tradings is less than necessary
* Setting the number of cycles to search for parameters.
* Performing automatic selection of parameters with storing all the results in the browser storage and the ability to save them as CSV files after testing, including in case of an error or page reloading
* Showing backtesting results on 3d chart to analyze the effect of various parameters on the result.
2. Upload external signals to Tradingview chart
Loading external buy or sell signals by timestamps from a CSV file
Optimization Methods
The sequential improvements optimization method is implement adjusting the best value already found. It does not perform a complete search of the entire parameter space.
The logic of it work is as follows. The current best state (parameters for max results) is taken. The first parameter is taken and all its values in the range are checked sequentially. If the best result is found, then further verification is carried out from this state. Then the next parameter is taken and all its values in the range are checked and etc.
The brute force optimization method implement backtesting all values in strategy space of parameters.
The annealing method is an optimization method in which the search for the maximum possible result is carried out in fewer steps https://en.wikipedia.org/wiki/Simulated_annealing
The method works this way: first, the best state and its parameters are determined. One parameter is randomly determined, then its value from range of possible values is randomly selected. The status in this value is checked. If it is better, then it is remembered and further parameter changes are made from it.
As the number of tests increases, the spread of parameter values decreases around those already found. That is, if at the beginning of testing the values are randomly selected from the entire range of possible parameter values, then as optimization is carried out, this spread decreases ("cools down") near current values. So in first phase of test - this method is search the most possible state around all space on the finish stage this method trying to improve found best state.
So that the system does not get stuck in one parameter area, as it happens with the sequential method, not one random parameter changes periodically, but all at once.
The random improvements method is the simplest. One parameter is randomly determined and then a value is randomly selected for it from the entire range of possible values. If the condition is better, then it is remembered. And then the parameters from this state are randomly changed.
The random method - always selects random values for all parameters at once (default)

This extension is open source and aims to reduce the manual operations of users when working with the Tradingview by implementing the technology of emulation of user actions. At the same time, parsing of the data displayed by the Tradingview's UI is used to obtain data. Extension do not interact with the Tradingview servers. If the interface changes, the extension may stop working and give errors.
The developer is not responsible for any possible violation by the user of the extension of the rules for using the Tradingview.

- (2023-07-10) Arthur Sergeev: Андрей Куминов, спасибо за эту работу, благодарю Вас. Вы сделали мою жизнь сильно проще и лучше! Спасибо Вам огромное, всех благ мира! Не бросайте апдейты ради любви и мира на земле! 20 июня 2023: Андрей, здравствуйте! ТВ изменили интерфейс, выдаёт ошибку: "Error: There is not timeframe element on page. Open correct page please". 22 июня 2023: Андрей, здравствуйте! Спасибо за быструю реакцию! Вчера, 21го июня работало без ошибок, сегодня снова вылезает та же ошибка. Подскажите кто-нибудь как пользоваться глубоким бэктестом, ведь, ведь после изменения настроек индикатора нужно либо перезагружать страницу, либо вручную переключить "Deep backtest" - такой функционал был всегда сколько помню опцию "deep backtest". Когда включаю глубокое тестирвоание, тестер делает первую итерацию и потом перебирает, считывая одни и те же данные первой итерации, которые застыли.
- (2023-06-21) Александр: выдаёт ошибку: "Error: There is not timeframe element on page. Open correct page please" Исправьте, пожалуйста.

- (2023-04-27) Mark Ronson: Thank you for good extension.
- (2023-04-08) hunter: Version 2.4 is not available，There is not strategy parameters input tab. Test stopped. Open correct page please Error: Could not find any strategy with parameters among the indicators. Add it to the chart and try again
- (2023-04-07) Ahmad Mulla: just work for few hours the (it was not possible to find a strategy with parameters among the indicators) please how to fix
- (2023-04-07) American History: There is not strategy parameters input tab. Test stopped. Open correct page please Error: Could not find any strategy with parameters among the indicators. Add it to the chart and try again.
- (2023-03-24) Addictive Break: I love the extension, but I confirm that there is a "There is not timeframe element on page. Open correct page please" since the last 2 days. Can you please correct it? Thanks.
- (2023-03-24) Eliot STEILER: Same ! "There is not timeframe element on page. Open correct page please"
- (2023-03-23) Daniil Lay: Absolutely love it, but there has been another TV UI change I assume, no timeframe element. Please open correct page

- (2023-02-04) 김수정: Thank you for your working. But pressing the test button does not proceed to the next screen. Since the Trading View has been updated something but the "Assistant" is not considering the update item, the "Assistant" also seems to need an update.
- (2023-01-17) Ting Daniel: Very helpful tool for me. But the function for deep backtesting was changed yesterday. So now the deep backtest function cannot be used. I hope the author can find a way to solve it. Thank you!

- (2022-10-11) Людмила Астахова: выдает ошибку: Tradingview calculation process has not started for the strategy based on these parameter values. Перепробовала все что можно, везде выдает такую ошибку.
- (2022-09-25) B V: I still cant get it to work. Still the same error msg on this and David's version. I believe they are the same. Do I need to update something on my end? I would like to use this but I am getting very frustrated with items that have David's name on them.
- (2022-09-23) wskg008 008: very good Thank you very much.

- (2022-08-11) Drew Pazdernik: Love this extension. I am, however, running into an error right now where it says, "There is not strategy param button on the strategy tab. Test stopped. Open correct page please. Could not find any strategy with parameters among the indicators. Add it to the chart and try again." Not sure why it says this as I do have my strategy on the board.
- (2022-08-11) Chan-TH GTA_Is_Inspiration: error 11/08/2022 This message show : "there is not strategy param button on the strategy tab.Test stopped. Open correct page please." Please fix it or advice. I'm doing the same thing I was doing while it worked so I'm pretty sure I'm not doing anything wrong. please help.
- (2022-06-24) Tyler G: Was running great and have been using it for a while but as of 06/24 I was getting the there is not strategy element on page correct page error.
