External Signals Strategy TesterExternal Signals Strategy Tester
This strategy is designed to help you backtest external buy/sell signals coming from another indicator on your chart. It is a flexible and powerful tool that allows you to simulate real trading based on signals generated by any indicator, using input.source connections.
🔧 How It Works
Instead of generating signals internally, this strategy listens to two external input sources:
One for buy signals
One for sell signals
These sources can be connected to the plots from another indicator (for example, custom indicators, signal lines, or logic-based plots).
To use this:
Add your indicator to the chart (it must be visible on the same pane as this strategy).
Open the settings of the strategy.
In the fields Buy Signal and Sell Signal, select the appropriate plot (line, value, etc.) from the indicator that represents the buy/sell logic.
The strategy will open positions when the selected buy signal crosses above 0, and sell signal crosses above 0.
This logic can be easily adapted by modifying the crossover rule inside the script if your signal style is different.
⚙️ Features Included
✅ Configurable trade direction:
You can choose whether to allow long trades, short trades, or both.
✅ Optional close on opposite signal:
When enabled, the strategy will exit the current position if an opposite signal appears.
✅ Optional full position reversal:
When enabled, the strategy will close the current position and immediately open an opposite one on the reverse signal.
✅ Risk Management Tools:
You can define:
Take Profit (TP): Position will be closed once the specified profit (in %) is reached.
Stop Loss (SL): Position will be closed if the price drops to the specified loss level (in %).
BreakEven (BE): Once the specified profit threshold is reached, the strategy will move the stop-loss to the entry price.
📌 If any of these values (TP, SL, BE) are set to 0, the feature is disabled and will not be applied.
🧪 Best Use Cases
Backtesting signals from custom indicators, without rewriting the logic into a strategy.
Comparing the performance of different signal sources.
Testing external indicators with optional position management logic.
Validating strategies using external filters, oscillators, or trend signals.
📌 Final Notes
You can visualize where the strategy detected buy/sell signals using green/red markers on the chart.
All parameters are customizable through the strategy settings panel.
This strategy does not repaint, and it processes signals in real-time only (no lookahead bias).
Input

How To Input And Offset CSV DataExample method of how to use an input text area to import, offset, and plot CSV data using an array. Note that when using this method there is a limit of 4096 total characters per input.
For working with data sets larger than 4096 total characters an alternative method of pasting CSV data directly within the script can be seen below :

external_input_utilsLibrary "external_input_utils"
Collection of external input utilities for conversion and other hacky functions
str_to_src(value) str_to_src - Convert the string value to the coresponding source series. It can be used to limit the "input.source" choices provided to the end user.
The most interesting part is that it can be used to overcome the "one input.source call limitation" for external inputs to your script
Parameters:
value : - The string equivalent to the source to be converted
Returns: series of the coresponding source
eval_cond(input, operator, value, defval) eval_cond - Evaluate the condition given an operator
Parameters:
input : - The input to be compared with. It can be an external input or a regular one
operator : - The string operator that describe the coparison operation
value : - The value to compare with the input. This can be a serries or a constant
defval : - The boolean value to return when 'noop' is selected
Returns: series of bool the result of the operation evaluation
Input Text Area to Array then Reshape Table█ OVERVIEW
Simple method to convert from input.text_area to array using str.split.
Reshape table using switch, not necessary must use matrix.reshape.
Might be useful pine script to replace input.symbol.
█ FEATURES
Table can positioned by any position and font size can be resized.
Reshape table and sorting array if necessary.

Fed and ECB Calendar by KziHello traders,
Here is a script that i've done for testing the timestamp and the input.time fonction.
You can see verticals lines blue and yellow.
The blue are the ECB meeting date (7 dates)
The yellow are the FED meeting date. (10 Dates)
// In the parameter you can enter the next rolling month date for ECB and FED
// I don't figure out how to add label / Txt on the lines
// And be carreful i don't put the real hours of the meeting.
Hx 9 Moving AveragesThis script is designed to handle and provide quick and easy access to up to 9 different moving averages in one indicator and one tab.
Basically, it leverages the 'inline' and 'group' arguments of the 'input' function to provide you with a simple and straightforward way to:
- define your favorite moving averages by choosing type, length, source and color in the same tab and
- decide which moving averages to display in one click on a checkbox.
I do not like to have to select the color of an indicator in another tab. So, I put everything in the Inputs tab.
In addition, I like to "linewidth code" my moving averages so that a sma has a different thickness than an ema for example.
To do so, just define the line width that you want to associate with a moving average type in the "LINE WIDTH" section.
Once parameters are set to your liking, just check / uncheck the moving averages you want to display / hide (and save your settings as default).
This script handles 9 different moving averages and implements sma, wma, ema, vwma, rma (RSI) and hma (Hull).
It can easily be modified to change the number of available moving averages or include other types of moving averages.
The default settings provide an example of commonly used moving averages with associated colors ranked from Hot (more nervous) to Cold (less nervous) with the exception of Hull moving average displayed in gray.
These settings are just an example and are NOT meant to be used as a trading system! DYOR!
Hope it will be useful.
Enjoy and please let me know what you think in the comments.
Line Chart SourceThis line charts uses simple input.source.
By default, use close, can choose open, low, high, etc.
