Based on a matematical model, is it really possible to discover a 100% win system? - page 3

 
You dont need a 100% winning rate system (R:R 1 to 1 I guess) a system with 52% winning percent and 200 trades a year will make you rich anyways.
 
You need to know your system's drawdown according to that you have to capitalise right amount of money. Even 45% winner system can make you rich with a good money management and sustainable growth model..

I have this question for a long time, what do you guys think? There really is out there a magical strategy that makes certain trade profit, with 

a 100% accuracy? if not what % range  you think is physically possible?

it's could be....you can trying to search in this web about signal provider especially on MT4. I have got some signal provider that have 100% win. I think they are have a certain strategy like get small pip to get profit.
 
100% might be difficult to keep in a long run (combined with a low dd) as there are other factors that can affect this performance (slippage, bugs ;) )... I am currently happy to hold a 99% win (even the most reliable hosting services have 99.9x up-time ... ).
 

You do not have to have a 100% winning system to be a successful trader. 

At what expense do you "win" when trading?

I could "win" 90% of the time and still "lose".

For example, i take 10 trades and win 9 at an average of 10 pips ie i make 90 pips.

My one and only losing trade is 100 pips ie even though i have a 90% win rate, i lose 10 pips.

I prefer to trade using basic risk management principles(R).

For example, lets' use a $10,000 account.

a/ decide how much is your "risk" per trade in percentage terms(1%,1.25%,2% etc), that is your R

b/ decide what your "reward" per trade is, 2R,3R etc.

Lot sizes will depend on what your R is.

On a 10k account, if risking 1%, you are risking $100 per trade.

If your "reward" is 3R,  you are making $300 per trade.

You can lose 70% of the time and still be profitable(7 x $100=$700 losses, 3 x $300=$900 win, profit $200).

 
thank you all for your responses, as you can see no agreement between the answers, so lets close this topic, i`ll try talking to a theoretical mathematician, he must have the answer.

In theory there is no difference between theory and practice. In practice there is.

Haven't read all the thread and maybe someone said the same, but it's not a math question but a logical question.

Suppose there is a magic strategy of 100% - and now suppose every one follows it.

Is it still 100%? of course not because forex is zero sum game (except broker earnings, which can be relinquished for simplicity).
so you can't make 1 USD if someone else does not lose 1 USD.

So - no magic strategy.

I was able to discover a 100% win system. But, it only have up to 51% win for longs and about 52% win for shorts.
 
Yes, only in MetaTrader Tester.... :)
