Good evening, I am currently using the following Stochastic Oszillator: iStochastic(NULL, PERIOD_M5, 7, 2, 2, 0, 1, 1, 0); The issue now is that once I use a Stochastic Oszillator (7, 2, 2) in Metatrader in a M5-chart the values vary enormously in comparison to the coded results. What I would like...

I found an older RSI divergence indicator named 00-RsiDiv_v104.mq4 (revised 4/26/09) that appears to work fine when you place it on a chart... However when I try to use this indicator with iCustom in an EA...it's extremely CPU intensive (60%+) and it is taking days to run the EA in the Strategy...

Hi all, I am trying to create a simple binary indicator, that returns value 1 when an argument is true, and 0 when the argument is false.  For example: #property indicator_separate_windowint start(){double SCORE;double MCCI=iCCI(0,0,14,PRICE_TYPICAL,0);double MCCI2=iCCI(0,0,14,PRICE_TYPICAL,1);if...

The backtests I am running over long periods are apparently not running to the full period specified in the strategy tester input. I can not think of any reason why this might be occuring. I have tried everything I know. Does anyone know what might be the cause? I am running backtests on EURUSD M5,...
i find it very difficult to enter my account and to trade with my money in account. what can i do?
I have developed a pattern recognition component that uses a TCP/IP .NET class (using a C wrapper) to get information to and from MT4, it works great on one commodity. I set it up so that I can have multiple TCP/IP clients speaking to the server (using different port#s) at once, so I could have 2+...

There seems to be a lot of conjecture as to whether it isbetter to trade short time frames or longer time frames. In fact it is often said that unless you can trade thelonger time frames then you shouldn’t even contemplate trading the short timeframes.   Now, I am not sure I entirely agree with...

If anyone who understands MT4 code has a spare ten minutes (or maybe this indicator laying around) - any chance of helping me?   I need to plot a simple one line/point (whatever) indicator below my chart which plots...
Hi, I run my EA on my home pc and login to my account by my Investor-Password: so no trades were possible! Is it correct that isTradeAllowed() still returns true (instead of false), and only if I set one of the two options "Allow live trading" to false it returns false? Thanks in advance, Gooly
I do not want to configure my Ea's with the standard input Box. the screen is to small and does does not allow for if statements. I looked at InputResizer by Mary Jane and it is very nicely done but it is not quite what I am looking for. I can and do use =MessageBox  but it only allows...

I seem to be able to code a number of different ea's that have a profit factor between 1.5 and 2.1 on eurusd daily charts but not any higher and not on very many other pairs. If I test these over the last 20 or so years of data they double the starting account but don't make much more. Doubling an...
