That is what many new merchants suppose and that is why over 90% of merchants fail.
If you wish to turn into a profitable dealer, you are going to should find out how correctly consider a buying and selling technique and regulate your notion of what’s backtesting end result.
Spoiler alert: Most profitable buying and selling methods begin off as mediocre and even poor.
However via continuous testing and iteration, they’re made into worthwhile methods.
Identical to profitable merchants are made, not born…profitable methods require an funding of effort and time.
The place to Begin
The very first thing to know about backtesting is that the majority profitable buying and selling methods did not begin out that manner.
An amazing buying and selling technique is rather like any nice invention.

This isn’t almost sufficient to determine how a method will carry out over totally different market circumstances and cycles.
So whenever you’re backtesting, get as a lot historic information as attainable.

It will not essentially be essentially the most worthwhile or essentially the most constant.
But when it meets your earnings wants, then that is all that issues.
A phrase of warning right here…
Many merchants (myself included) begin out with unrealistic targets for his or her methods.
So set a aim, however you would possibly end up having to regulate what you anticipate out of one buying and selling technique.
You might need to commerce a number of buying and selling methods or markets to get the outcomes you are on the lookout for.
Do not get discouraged nonetheless, in the event you hold working the outcomes will come.

Once more, you most likely will not get a brilliant worthwhile backtesting end result in your first strive.
The secret’s to have the ability to spot the diamonds within the tough.
From there, you’ll be able to work on creating every technique to its most potential.
