Looking for a specific setup back in time with an EA

The smothness of the curve and the drawdown in relation to the profit it made. But be careful: the backtester doesn't plot or otherwise record the drawdown that happens between two trade closings. The curve should contain several hundred (better ...

Why we have innovated so many trading system?

99% of them dont work because they are not tested on sufficiently enough data. They are not systems, they are only ideas for possible systems and almost all of these ideas turn out to be unusable. Finding a working system is hard because there are ...

5 day and 35 day sma on 1 H charts?

Make heavy usage of Print() for debugging. Print() is your best friend. When you suspect that iClose(foo, bar, shift) gives wrong data then print out before *every* call to the function foo, bar, shift // to see what you are actually feeding to this ...

"Phantom" Close!!

It isn't the language, it is the community that is wrong with such languages. There simply are no experienced coders around, there are mostly beginners trying to teach other beginners, none of them has ever learnd programming. Just look at the code ...

Learning to Program MQL4/5

I suspect there is still one of these hard to find bugs in your own program where some variable is not updated correctly, initialized wrongly, one of these malicious typos (i instead of 1), something that happens only in a seldom used if branch, ...

"Phantom" Close!!

Because you haven't seen something doesn't mean it doesn't exist. * Closing a buy is equivalent to opening a same size sell. * Closing a sell is equivalent to opening a same size buy. * It doesn't matter which buy or sell you close first, only the ...

Synthetic Hedging Script, Conforms to new CFTC regulations

I fully agree! What we are seeing in mql4 programming is what i call the PHP effect: A lot of noobs with absolutely no background try to learn this domain specific language as fast as possible. The forums are full of blind leading the blind and the ...

Learning to Program MQL4/5

I would suggest doing the array resize in init() if numOfBars doesnt change during operation or only call it when numOfBars really has changed so it doesn't call this function on every tick. ArrayResize() is quite expensive, especially for bigger ...

arrays in mql4

I assume you want the close of a bar. In MT4 this is the last tick that would belong to this bar and unfortunately it is not easy to trigger something on the last tick because you never know if it really was the last tick that just came in, instead ...

If there is a trend then it is not random. Random data would be for example price(t) = price(t-1) + e(t) where e would be normally distributed random numbers with zero mean. In your example you just assume another constant term added to this, the ...

Inescapable Truths

What is the intended use for this? Why not just close the EURUSD position instead of paying two additional spreads plus the swap and unnecessarily use margin? To me this makes just as much sense as // this will work even faster while (equity() > 0){ ...

You didn't ask any question so far, you are just permanently stating absurd things that already have been formally proven wrong. Who told you it would be isomorphic? The mapping simply must be defined, thats all! The mapping is surjective! Here ...
