Zen_Leow, You are great. Your code is quite efficient and precise. I respect you. I found several misunderstandings about thread starter's intention, so I deleted mine. It's just confusing. Regards.

Arnold49, As I see, your EA will never manage trades on other symbol charts. If it really happend without any other EAs, the only possibility left is you used built-in trailing stop by MT4 terminal. If negative, I have no idea about that, sorry.

I can't say anything certain with only a piece of code above and without knowing what settings the management EA have, but, Yes, It's not at least "chart specific" but only "symbol specific". I don't think it will manage GBP/USD trades when you are ...

Arnold49, Ok, if so, OrderSymbol() == Symbol() does not manage trades only on the chart the EA is attached. If you attach it on EURUSD chart and you are opening 5 other EURUSD charts, it will manage trades that is opened on all other 5 charts also.

You need to use one more condition to specify a trade by magicnumber. if(OrderMagicNumber() == MAGIC) Some EAs don't add magicnumber to the ticket when they send open order. (If they don't, magicnumber become 0 that is the same as manual trades.) In ...

Nuozek, As I understand, the meaning of Oftimal f　(Kelly) is the followings. 1) Optimal f is a theoretical value to maximize your equity. If f>0, the most efficient way to bet is always bet Equity * f. (It's only theoretical and considering it's ...

As a matter of fact, I know there is a bit more to consider although I didn't code it for my recent utility EA. It's about how to deal with breakeven trades and what I call "scratch trades" that is nearly breakeven trades that only gained or lost ...

bug fix — I have fixed some possible zero divide errors and have posted it to #1.

Nuozek, I'm glad if you solved the problem. By the way, It seems that your Kelly criterion is different from Kelly formula I know.... Kelly formula I know is f = ((R+1)*P - 1) / R *R = Profit / Loss Ratio = Average Win / Average Loss *P = Winning ...

Ronald, If you mean I didn't define the rules what step value should be used, correct. (Main intention then was to reduce price steps for higher timeframe as I wrote.) This is basically the same problem as what multiplier value should be used. They ...

Hi pinchapip, Here is a solution I always use. int DQ_ADJUST [] = { 0 , 0 , 1 , 10 , 1 , 10 , 100 }; int DQADJ; //+------------------------------------------------------------------+ //| init ...

Hi, I'm coding on Alpari(UK) Demo MT4 Build 220 (5 digits) and have no problem. Can you see any errors in your journal or expert tab (e.g. zero divide) ? *I forgot to tell you that the picture I attached above is FXDD Live (4 digits) and both works ...

If this function is meant to return average winning/losing size in pips per a (winning/losing) trade, it should be like below.(not tested, it may contain some bugs) Regarding to zero divide, it can happen only in the case when EA_Executed_Trades == ...

Although I didn't inspect all your codes, but there is one thing you have to know. This is an explanation you can see at Metaeditor's search function. In brief, "MODE_HISTORY" is ignored if you use "SELECT_BY_TICKET". So when you use ...

Here is an indicator that shows Weekly & Daily HL. You can hide Weekly (or Daily) HL lines if you don't need it. If you want the lines to be thinner, change indicator_width to 1.

Just imagine someone steal a monograph(a paper ,a novel or anything) you have written and claim that he wrote it. How do you feel ? In short, decompiling just means stealing coders property. No excuse can be acceptable. Sometimes it's simply called ...

Thank you for the reply. I'm looking forward to it.
