Good day, colleagues. please help me find an Expert Advisor – a kind of Martin, so that when the price goes to minus the first position, it opens a double position, but only in the opposite direction. for example: 1st BUY order (1 lot) in the red means the 2nd order (2 lots) is opened for SELL… thank you in advance

This is an ordinary martin coup, it is not reverse, the codebase is full of such.

Support. For some reason, everyone believes that it is necessary to either constantly average, or constantly turn over and do nothing else. And then they estimate the maximum number of knees for such a moronic strategy and say that a very large deposit is needed.

For what? Maybe not enough, maybe enough.

You ask for something specific !

That is, proceed from:

The probability of one win(say, 0.4-yes, it can be less than half, because we are beginners, plus you need to take into account the spread swap)The number of desired series without draining.On each series – you win your bet (say 1000)The probability of not merging in all these series. For example, 0,99With these data , we must withstand a drawdown of 23 losses, and, therefore, we must have a deposit of 8M bets. Having such a deposit – we have a probability of a single win of 0.4 (significantly less than half) – nevertheless, for 1000 Martingale series we will never merge with a probability of 99%. (But still, there is a 1% chance that in one of these series there will be 24 losses in a row, and we will merge).

To ask other baseline data (three values) and the required length of the damages are easily calculated.

martin, even with 20 knees, has a good chance of a “bad series” for the foreseeable future.

and 5t failures to catch-in general elementary. And a depot even for 5 needs at least 2^6*(500+1.5*spread)=from 32,000 initial point lots and plus a collateral cushion and something for swaps

5 knees with a step of 500 is not enough?

Just for fun

## laryx

You can do that. Moreover, for Martin, the first transaction can be made “on a coin” – you will still be in the draw.

The amount of the deposit on Martin is very easy to calculate, and it is very impressive. If the deposit amount is less-the drain is inevitable.

## beckham21

do you propose to sit and flip a coin? )))

## nektomk

you may not believe it, but the 2nd and further martingale orders can (and it’s even better) be opened in a random direction.
