It doesn't have this option. You will have to write some code (a custom indicator) that will *calculate* log(price) and then plot it into an indicator window. Unfortunately MT4 does not support logarithmic scaling of the y axis on its own.

How to change the price scale to log??

No! There is no need to do anything with flatfiles. For example: RGetDouble() or its shorthand Rgd() get a double value from an R vaiable or expression RGetVector() or its shorthand Rgv() get an array of double from an R variable or expression. ...

You should include your open positions too (which means instead of using the account balance you simply use the account equity). Then it does not matter whether positions are open or not. The Account equity will always tell you exactly how much you ...

Take the value of the account equity (and completely ignore the balance, it is meaningless anyways). At any moment in time you can look at the account equity value and it will tell you exactly how much money you currently have in the account. From ...

The Euro can disappear only once in its entire lifetime, so the disappearance of the Euro can be considered a very rare event and most likely this event will be very difficult to trade. So I would not even try to predict the exact time of this event ...

Is the Euro doomed?

The smaller the stops the more the transaction costs come into play, But if your system is able to overcome this even on smaller timeframes then I see no reason why you should not do it. I am still interested to learn how your trading strategy looks ...

Don't waste your time trying to make the parrondo paradox work in trading. It won't work. If it were possible then there would be an EA for it and it would be the holy grail by definition. Every hedge fund, every bank every trader would use it and ...

I don't know what YOU are seeing, but an angle between time and price is simply not defined, cannot be defined, therefore it cannot be calculated. What you might see in some nonsense indicators that claim to measure angles are only some fantasy ...

...and R can easily be integrated in MQL4 programs: #include <mt4R.mqh> int init(){ RStart(); } int deinit(){ RStop() } int start(){ Rd("baz", Close[0]); // assign double Rx("foo <- 42 * baz"); // execute R code Print(Rgd("foo")); // get double }

It does not contain any code for trading. It is some kind of indicator. the only reason I made it as an EA is to be able to easily run it on past prices in the backtester and because indicators are not allowed to call long-running functions, this ...

"Gann angle" sounds like BS. There is no angle in a price chart, not even Gann can change this. There simply is no such thing. The only type of "angle"-like measurement you can ever calculate in a price chart is called slope and it is measured in ...

No. You are flat and the first trailing stop is a buy stop (or sell stop) to bring you into the market and the second one will close it again.
