We've created an easy-to-use Kelly Ratio script that you can quickly add to any chart on TradingView.
Once you've added the indicator, you're going to want to change the settings match your current back test results.
Click the format button beside the indicator on your chart.
The first setting is the percent profitable, set this to match and click OK.
The other two settings can be found by navigating to the Performance Summary Section of your Strategy Tester tab. Scoll down to find the Avg. Win Trade and Avg. Lose Trade results.
Once you've matched all the settings, and click ok, the plot of the script will be the recommended percentage of your portfolio per trade.
In my case, the result was 9.4451, rounding up to either 9.55% or straight to 10%. My next trade, according to the Kelly Ratio, she risk no more than 10% of my portfolio per trade.
