Script that Opens/Closes charts

I am wondering if there is a script that can open and close charts available

something that would open currency x and find time period y and start the EA on the chart

nope, mt4 doesn't give those options

What about at least changing the time period of the chart?

nope

There are key senders that will do some of that. For example, if you already have a chart open, send Enter, then the symbol, time, or time-date (see hotkeys for details), and enter again. Same as with the keyboard. And you can run scripts and (I think) EAs from a hotkey. See the sticky on tips and techniques above.

Here is what I want to do.... if I can't open and close charts, then I will want a way to have it trading only x amount pairs at once and at the most efficient time period

so I see that I can do enter, (Symbol), (time period) so Symbol and time period can be variables

How does this work if I have 22 charts opened... I can grab market data based on some scripts and run my calculations that will tell my system x and time period y.... so if I can't open new charts, then I need to be able to go to the correct chart and change its time period

basically, I was looking at an EA that I liked the theory, but I am wanting to make it more dynamic and diverse... it is complicated and I am trying to learn some complex coding mechanisms while trying to program this EA to fit my style

you can pull data from any symbol and any timeframe programmatically with functions such as iClose, iOpen, etc. each of these functions require the symbol name, the time frame and an offset. Any of the indicators can do the same. No need to have charts change times.

so, lets say I want to trade EurUsd

I have a ratio that is checked between the 1 min, 5 min, 15 min, etc.

Lets say the ratio returns indicate that I should trade the 5 min chart... however, my chart is currently opened to the 1 minute.... I have an indicator that I place on the chart and the EA should open a trade when it hits a line on that chart... I don't want it hitting a 1 min. line if 5 min. is the optimal time period

sure you can do that. I have EA's that sit on the 30 min chart but monitor the 5,15,30 and 60. it makes entry on the 5 and then progressively hands over control to higher time frames as the trend progresses. I only have the 30 min chart open.

interesting... how to you handle the handover?

I am trying to get a clean code that will compile before I add in the complexities, but have 2 of these errors

'(' - function definition unexpected

it is a single EA there is nothing to handover. Everything is done through iCustom function calls along with iclose,iopen, etc etc.


Double click on the error and it will take you to the line that has the problem. Without seeing the code it is just guessing at what the problem is.

Ok, got it fixed... now I can dig into using the iCustom functions

ok... have the variables now set with iCustom function

Now I probably need to write into the indicator to check some ratios that also need to be passed

I want a ratio:
how many times it hit line 1 and went to line 0/line 1 and went to line 2 over y bars at each time frame

once it hits that line, it isn't reset until it hits line 0... so if it is line 1, hits line 2 and comes back to line 1, then to line 0.... it would be a 1/1 ratio (line 1 only counted once per reset)

additionally, I want track the average duration in minutes from line 0 to line 1 and back to line 1... so if it hangs between line 1 and line 0 then returns without hitting line 1 the clock continues to run

the ratio I want is (ratio/time)*(pipsdistance*valueperpip)... so if the line 1 to 0 over line 2 to 1 ratio is 3/1 and it takes 10 minutes then it is 3/10*((how many pips away from line 0 is line 1 when first hit + how many from line 2 to line 0 when first hit)*value of each pip)

so if each pip is worth $1 and the distance is 10+11+9 pips(3 times it hit) from line 1 and 25 pips from line 2 then it would be 55 pips * 1..... the ratio score would be .3 *55 or 16.5 for that currency and time frame

Since all of the more complicated EAs are ex4 files, I don't get to see how they are doing some of the things I need to figure with MetaTrader programming...

Here is my setup:
I have two indicators with 6 buffers each... although one buffer on each is measuring the same line (the center line) and the other 5 are measuring levels that I would want trades opened up at

there is a bar count feature in the indicator... do I need the same variable in the EA to input into the iCustom function? I should input this at the top of the start area for the EA, correct?
=======================================

There is plenty of available EA source code if you look in the right places. There are other metatrader forums.
