Looks interesting, did you bet the ranch? All charts and indicators are lagging. So you won a trade, next time bet the ranch and report back please, i would like to see the results.

If I just have to name X amount of years then probably 10. But it's more complicated than that - the backtest period needed is a function of number of rules and trades per year. If the method is extremely simple, it doesn't need a 5000 trade backtest but if it's curve fit then even 5000 might not be enough. I'm saying curve fit because whether we like it or not, all our stuff is curve fit to some extent.
we look for for specific set ups /patterns we are used to , but can't see the trees from the forest , we can not look for the unknown or other risks . cognitive bias deludes us from seeing anything else , other than curve fitting as ok.
People who can trade just trade, building their wealth over time. They don't feel the need to go onto trader's forums and brag about it or charge others for some dubious "service".
yes, no matter how much of a sure thing, manage risk. There could be something lurking in the dark deep trade that can jump up and bite ya where the sun doesn't shine...
my trading is only about risk management ,if risk higher than 1 % , I won't trade looking for 250 ticks profit a week option strategy
