There is something written about pointers to memory blocks and something that sounds like Pascal strings, it doesnt really make sense (maybe it makes more sense in the russian original) and they dont talk about modifying the string for later use by ...

Yes. Goto http://codebase.mql4.com/6217 and download and install offline_charts.mqh. Although i primarily wrote this library for creating realtime equity curves it mainly consists of generic functions for dealing with offline charts. It contains a ...

Is it possible to create a new symbol in MT4

You can safely optimize with "Open price only", your EA should only trade on the first tick of a new candle. Any other ticks should be ignored anyways. Did you already try my reference EA from Post#1? It can be optimized from minus a few hundred to ...

You cannot be sure how metatrader handles strings internally. Maybe your DLL will only receive a pointer to a C compliant (null terminated) copy of the string that will be discarded after the call and internally it stores strings in an entirely ...

the original version on H4 is still long: image

I have seen a library somewhere on mql4.com that does this by remote controlling a second MT4 instance. I am already thinking about writing something similar for myself but using only one MT4 instance (maybe using AutoIT scripting or directly using ...

Be careful with the words "in the long run". I believe that there is nothing that will work forever. However, there will always be something that currently works and will continue to work at least until tomorrow or even until next week. If a system ...

Why don't you tell us what is contained in the variable open after the call? Are you sure that you can pass strings as pointers (as you obviously do it), have them changed in your DLL and then still working in MT4 without producing an access ...

Strange String behaviour

The reasons are: (1) There is a certain amount of random noise in the market. (2) There simply are not many mechanical systems for exploiting the ever changing little non-randomness that will continue to work forever without the need of constantly ...

what can keep a working strategy to always have a high probability to win each trade?

This very same problem appears with almost every mechanical System. It also happens when you are just riding a trend: When will it end? The easiest way to find out is to watch for signs of reversal, see how the equity curve looked at the end of such ...

Of course it is some sort of "curve fitting"¹, but not in the negative sense of this word. Every System is created by fitting a model to the reality, some work for years, some stop working when the market changes and new models or new parameters ...

Yes. 61 with negative correlation as mentioned in the first post works perfectly for EUR/USD, H4. This one is the same system on H1 with parameters adjusted so that they work for H1. Since not only the shift is adjustable but also the sign of the ...

a shift found by fitting it to only 3 months H1 data worked also during 4 other months. This should also work forward. I just started a new forward test on EUR/USD H1, magic_shift found by fitting it from March until now is 192, positive correlation ...

I just made an experiment on H1, I didn't cherry pick a certain period, I just used the time interval that happened to be already set in the tester from some other experiment, switched to H1 (i mainly use H4, didn't extensively test H1 yet) and ...

But isn't that only possible if i can find a hypothesis for almost every possible outcome? In your example you had 10 coin-flips and 1000 coin flippers. I'm testing over hundreds of coin flips and have only 200 coin flippers. I have found some pairs ...

I count 11 more bars (44 hours) long: image But if I look at the equity chart (the small chart to the left) then I dont think all of these bars will go up. There is some room for a retracement at the equity chart, but if you would have been long ...

Its the built in accelerator oscillator of mt4. Unfortunately it can not be shifted when put on a chart to visualize it. My EA draws a vertical line at the positon of the shift to help you find the correct position. Maybe someone wants to write a ...

This may be true, but looking at the history it seems that the same shift can stay intact many months, the current shift has been in place for a year now. Unlike many other systems with dozens of parameters, leading to zillions of possible ...
