is simply the permissible size of the new rake on the new car model.
The fact that the rake is bound to happen is common knowledge. And that any EA settings (by optimizer or by instinct) refer to the irretrievable past is also understood by some people.
And this is about the optimizer.
We should not forget about already known methods of strategy checking:
1. If a strategy gives positive results in the tester for a period of two years, then increase this period to five years...
2. After one year, repeat the test of this strategy without changing the settings - the so-called forward test...
These time-tested actions greatly increase trader's Confidence in his profitable strategy.
But to determine the "grail" such properties are not enough...
The Grail is when you have only Profit on any open trade, not less than the spread! I.e. no drawdown, no breakeven!
It's easy - you have about 100-500 million in cash, you buy buys, you sell the shares at a 90-95 per cent commission. Just keep trading and checking on the partner.
It's about the same guys Peter lumped together, and in a very simplified way.
The Grail is when on any open trade we have only Profit, not less than the spread! I.e. no drawdown, no break-even!
Almost the same, only in other words: when the absolute drawdown in each trade is zero.
Don't forget the already known techniques for checking strategies:
1. If a strategy yields positive results in the tester over a period of two years, then this period should be extended to five years...
2. After one year repeat the test of this strategy without changing the settings - the so-called forward test...
These time-tested actions greatly increase trader's Confidence in his profitable strategy.
But such properties are not enough to determine the "grail"...
The principle proposed by you-know-who (it's plastered, but not quite, according to tradition, or what the heck), it is not applicable.
well, it is impossible to change 10% of trades in the past into the opposite. And even their profitability/loss cannot be changed. What they were is what they are...
you don't need to change past trades themselves
you only need to worsen the indicators from your state
if after worsening the MO remains positive then it is royal
if negative - then go to the factory
applicable almost everywhere for a long enough period
it is not necessary to change past transactions themselves
you only need to worsen the indicators from your state
if after worsening the MO remains positive, it is a royal
if negative - then go to the factory
applicable almost everywhere for a long enough period
but it is better to forget everything that is written here and go to the factory
To add to the riddles of the modern "market":
Time to open your own bank. Or an exchanger.
MO is such an MO.
MO from an optimiser is one thing, other is another.
