If you don't want to lose all your money due to some random strategy you found on the Internet, here is a warning:
All trading involves high risk; past performance is not necessarily indicative of future results. Hypothetical or simulated performance results have certain inherent limitations. Unlike an actual performance record, simulated results do not represent actual trading. Also, since the trades have not actually been executed, the results may have under- or over-compensated for the impact , if any, of certain market factors, such as lack of liquidity. Simulated trading programs in general are also subject to the fact that they are designed with the benefit of hindsight. No representation is being made that any account will or is likely to achieve profits or losses similar to those shown.
16 trades, percent profitable: 75%
profit factor: 16.9
12 trades, percent profitable: 83%
profit factor: 37.7
9 trades, percent profitable: 100%
(profit factor: highest)
And many other settings using different lengths are very profitable in backtesting on Tradingview, too.
