I never use investing com but it popped as an ad for their ProPicksAI which claim to outperform pretty much everything, like they claim to beat Warren Buffet by using his picks...which.....let's just say it made me read the disclaimer.

Here is the disclaimer in nearly impossible to read grey small font:

"Our backtesting models are based on data sourced from third party data providers, and we do not guarantee that this information is accurate or complete. Furthermore, these data points, formed in hindsight, do not account for actual trading influences or unforeseen economic and market events. Moreover, since these are not real trades, the results might not account for certain market factors, and may not reflect the potential impact of various economic conditions. Backtesting can be adjusted until past returns seem optimal, so real-world results may differ. Although the results include factors like reinvested dividends, they may not always reflect other aspects like potential transaction costs or other fees, which may affect the return. In addition, no cash balances or cash flows are included in these calculations. While actions have been taken to minimize biases, these biases cannot be eliminated and may affect real world results. In light of the above, users should take caution when considering making any investments based on the aforementioned strategies and results."

How about you just tell us in large bold font that you snooped the data with lookahead bias so that you can sell this shitty service and fleece innocent retail traders? That would be nice for a change.
