Looking for a specific setup back in time with an EA

  • First Post: Nov 11, 2009 12:51am Nov 11, 2009 12:51am
I have a question about what’s possible to do with a script or an EA for MT4.

I want to know if a specific setup has happened in 2008 or for the last 6 month and how many times it has happened.

Is it possible to collect this kind of information back in time and write them into a CSV file?

Thank you for your reply in advance.

Scripts are for one time tasks such as you describe. EAs are for executing the same thing over and over again. I often do as you describe without exporting the data to Excel. Instead I like to mark the charts with my results and look at them visually. But exporting the data is easy.

Ok I will send you a description of what I need it to look for.

Thanks!

Search this forum for the "TotalRecall" indicator. It was an experiment done by be that tries to identify similar price patterns in the history of the same pair and plot the best matching ones into indicator windows.

Maybe this is of some use for you, maybe as a starting point for further improvements or modifications.

Let me call the bar I’m talking about “my bar” to make it easier to understand and easier for me to explain.

#1 I want to look for a bar (my bar) that has a lower low than the previous bar and has a down close.

If the bar next to “my bar” reach a high that is equal to the high of the previous bar
of “my bar” and then I want it to write date, hour, min and pips*
(*see extra feature) to a file that I can import to Excel.

And then I want the opposite:
#2 I want to look for a bar (my bar) that has a higher low than the previous bar and has a up close.

If the bar next to “my bar” reach a low that is equal to the low of the previous bar
of “my bar” and then I want it to write date, hour, min and pips*
(*see extra feature) to a file that I can import to Excel.

It can be two separate scripts that create one file each or one script that can create to separate files to Excel.

I don’t know if it’s possible in scripts to make input fields, but if it is I want to have two input fields one for “Date start” and one for “Date stop”.

Extra feature: I want to know how many pips I could have made taking this trade so I need it to measure the down/up trend.

The way I see this could be done is by measuring the high of each bar after “my bar” and keep doing that until there is a lower high than the previous bars high and the minus this # from the entry price which should be where they had the same high.

And the opposite for #1 in this example with the low.

In your description, you state that #2 is the opposite of #1, but then say that I should look for a higher low for #2 but #1 is looking for a lower low. The opposite of lower low is higher high, is this what you meant to say? Or is #1 supposed to be a lower high?

This was easy to do and is almost complete.

Last line should have been "And the opposite for #2 in this example."

Doesn't it make more sense?

Yeah easy for you cause you know how to code this ;-)

I am going to assume that the script should look for lower lows and higher highs. Let me know if that is wrong.

For verifying my results, I marked the chart with arrows. I am going to leave this logic intact in the script. If you want to turn it off, change this line from true to false and recompile. I think you will want to keep the arrows annotating once you see how effective they are.

extern bool showArrows = true;

If you have any other programming requests related to this, let me know. You can use this forum or PM me.

CodeMeister I'm very happy that you want to code this for us. Thanks!

Sorry it me. Let's try again.

#1 : "my bar" should have a lower high than the previous bar and
#2 : "my bar" should have a greater low than the previous bar.

Do I need to copy it to the experts folder and then drag it on a chart to start it ?

Here is the corrected version with higher lows and lower highs. I am attaching both the source and executable files. Copy both to the experts/scripts directory, double click in the Navigator window to run it. It can be run on any currency pair for any timeframe. Don't run it on an existing chart with other indicators. If you need any assistance, this is a good resource:

The output CSV files will be located in the experts/files directory and be named something like EURUSDLongMyBar.csv.

CodeMeister, you're the man! Thank you for taking the time to code this for me and for the explaination on how to start it.

Let me test it :-)

Here is the modified script which allows for a date range. Just change these lines to get the desired range (YYYY.MM.DD).

extern string fromDate="2009.10.1";
extern string toDate="2009.11.1";

That was fast.
