15 de fev.

Happy Trade,

here you get the opportunity to backtest any of your indicators like a strategy without converting them into a strategy. You can choose to go long or go short and detailed time filters. Further more you can set the take profit and stop loss, initial capital, quantity per trade and set the exchange fees. You get an overall result table and even a detailed, scroll-able table with all trades. In the Image 1 you see the provided info tables about all Trades and the Result Summary. Further more every trade is marked by a background color, Labels and Levels. An opening Label with the trade direction and trade number. A closing Label again with the trade number, the trades profit in % and the total amount of $ after all past trades. A green line for the take profit level and a red line for the stop loss.

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:

Pine Script®

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

Pine Script®

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.
