if i want to develop a system with 20 different moving averages, that goes from 2 to 20 periods, and try to find the best configuration, i have to

try at least aprox 10 500 000 000 000 000 000 000 000 different possibilities or i'm wrong? The fastest supercomputer today

calculate only around 100 quadrillions operations per second, so he would take years to calculate all these possibilities,

my question is:1- there is a way to test all these possibilites using some kind of approximation that really works, or it's impossible? 2- if it's impossible how can one say that moving averages

doesnt work, if its impossible to test all combinations of even small periods? 3- what's the best way to think in create systems if you deal with so big numbers?

You can buy MQL5 cloud network to speed up the backtest process.

However, it does not mean it will be profitable in the future even if you manage to find a combination that works because you are basically curve fitting it. Given the amount of possible combination, some of them will definitely make good money.

Infinite monkey theorem states that a monkey hitting keys at random on a typewriter keyboard for an infinite amount of time will almost surely type a given text, such as the complete works of William Shakespeare (source: wikipedia). If some signal providers who use tens or hundred of accounts with different indicator settings can eventually find one of them making big money hence selling as a signal, then you could definitely find some of your MA combinations making big money too.

Just like given enough number of people playing slot machines, some of them will eventually hit a jackpot. But that does not mean they found a way to hit a jackpot and keep repeating it. They are just lucky.
