I am new at trading and I found the EA named "Expert+10" here on the site. This EA only works well with EUR/USD because it is set to a particular time frame, "I guess," specific to the EUR/USD. I was wondering if there was a way to set it up to trade the previous days high and lows on any currency...

What's the difference ? I guess G lasts 4 weeks if not visited, while S lasts forever. Both are stored on harddisk. G can be deleted with MQL, what about S ?

When backtesting (using the tick method) the highs and lows on other timeframes get all screwed up. Is there any work-around to resolve this? My EA uses various timeframes at the same time, and it needs the highs and lows to be correct.

Hi, I'm not a coder, just a user, so please help me understand why we are "stuck" with 5 min or 15 min time frames or 1 hr and 4 hr in MT4. I know we can create out of the ordinary time frames offline, but "live" candles are what I trade with. Does someone in this forum have an application (for...

First off, I know Raptor that you have raised this issue with me before, but I cannot remember where you wrote it, and, more importantly understand where I am going wrong? As far as I am aware I was writing it correctly so that the EA attached to any corresponding Pair will be able to always work on

Hello all, First post so please direct me to the right place if you need to. Im not sure if I need a script to do this but please let me know if I do (and provide solution if possible). I am trying to create a simple mql4 program or script that will place trades based on the MA. There is an...

Hi, I'm planning an EA, which will send a series of orders if trend develops well. The latter orders depend on former orders. And orders's sizes are not the same. The very first order's size, especially, is quite different. So, I'm thinking: what if MT4 re-connect? ----even if I try to keep it...

Hi All, Please see attached mq4 file. I have modified this to display charts in 4 TFs at once in the same window, from the original (correctly working) mq4 that only displays one chart at one time, as here: http://www.stevehopwoodforex.com/phpBB3/viewtopic.php?f=45&t=629 no. 2 in Post #1 (Currency...

Hi, Looking into ZigZag code, there're 3 parameters: extern int ExtDepth=12; extern int ExtDeviation=5; extern int ExtBackstep=3; What do they mean? Apparently it's not what I'm thinking ---- for example, when price moves more than 30 pips, it begins to draw a swing high/low. But from a beginer's

Hello, I have a EA that I found on the forums that had some math errors and such, but once corrected works on the Demo server without any problems and does what I want.
