Usage

1) You need to know the name of the boolean (or integer) variable of your indicator which hold the buy condition. Lets say that this boolean variable is called BUY. If this BUY variable is not plotted on the chart you simply add the following code line at the end of your pine script.
For boolean (true/false) BUY variables use this:



And in case your script's BUY variable is an integer or float then use instate the following code line:



2) Probably the name of this BUY variable in your indicator is not BUY. Simply replace in the code line above the BUY with the name of your script's trade condition variable.

3) Save your changed Indicator script.

4) Then add this 'Backtest any Indicator' script to the chart ...

5) and go to the settings of it. Choose under "Settings -> Buy Signal" your Indicator. So in the example above choose <Stoch RSI: K>.
The form is usually: '<name of your indicator> : BUY'. Then you see something like Image 2

6) Decide which trade direction the BUY signal should trigger. A go Long or a go Short by set the hook or not.

Now you have a backtest of your Indicator without converting it into a strategy. You may change the setting of your Indicator to the best results and setup the following strategy settings like Time- and Session Filter, Stop Loss, Take Profit etc. More of it below in the section Settings Menu.

Appereance

In the Image 2 you see on the right side the List of Trades. To scroll down you go into the settings again and decrease the scroll value. So you can see all trades that have happened before. In case there is an open trade you will find it at the last position of the list.

Every Long trade is green back grounded while Short trades are red.

Every trade begins with a label that show goLong or goShort and its number. And ends with another label again with its number, Profit in % and the resulting total amount of cash.

If activated you further see the Take Profit as a green line and the Stop Loss as a orange line. In the settings you can set their percentage above or below the entry price.

You also see the Result Summary below. Here you find the usual stats of a strategy of all closed trades. The profit after total amount of fees, amount of trades, Profit Factor and the total amount of fees.

Settings Menu

In the settings menu you will find the following high-lighted sections. Most of the settings have a question mark on their right side. Move over it with the cursor to read specific explanation.

Input Signal of your Indicator: Under Buy you set the trade signal of your Indicator. And under Target you set the value when a trade should happen. In the Example with the Stochastic RSI above we used 20. Below you can set the trade direction, let it be go short when hooked or go long when unhooked.

Trade Settings & List of Trades: Take Profit set the target price of any trade. Stop Loss set the price to step out when a trade goes the wrong direction. Check mark the List of Trades to see any single trade with their stats. In case that there are more trades as fits in the list you can scroll down the list by decrease the value Scroll.
