How to backtest Renko?

Quoting sangmane
Hi bj,

Below is a script that will convert history file (in the format *.hst) to CSV.

Offline chart's data is saved in history file. To open it you should use FileOpenHistory(handle,..).

Set FileNameHistory to the name of the history file, excluding any directory path. MT4 will always lookup history file in history folder.

Output CSV file will be in experts/files folder

Let me know how it works.

Could you please let me know how to export the offline chart in a history format - *.hst as the script I am uses saves it in .csv, or I should simply rename it?

Thanks for your help!

What do you want do? Convert offline chart (hst format) to csv OR convert csv format to hst format?

HST2CSV is for converting hst to csv.
All that I need to do is have the renko bars data in a .csv. I need to use the open and close values as well as the time, but I cannot seem to find a way to do that.

Suppose that your renko bars is generated on EURUSD chart, RenkoTimeFrame = 2,

Run the script with FileNameHistory=EURUSD2.HST, FileNameCSV = EURUSD2.CSV.

Once the script finished, you will find a file named EURUSD2.CSV in experts/files folder
Oh, thanks, it worked this time. Still the data that was exported is not correct. Here is the file that I got, although I put the script on the offline chart (2 minutes) I got the following export data file that I attached. It seems to be hourly data..
Attached File(s)

Use FileNameHistory to tell the script which pair and TF you want to export.

If FileNameHistory=EURUSD2.HST, this script will export history data of EURUSD M2, regardless what chart you put the script on.

Thanks in advance...

I am still trying to export the data from the Renko offline chart to a file.
If you use procedure described in first post to generate Renko as standard TF for backtesting then you can simply export CSV file from the history center - press F2. No special script is needed.

Hi Folks

I have following points about problem we see in Back testing and in my opinion it is due to following:

 

  1. We all download history data from MetaQuest, regardless of our Broker.So technically, we are getting away from our broker data and testing on other data, and when we test it Live with our broker, the results are found different.
  2. There are price feed in-consistencies in some of the Brokers, which results in wrong results for our strategy as well.

My opinion, we could Back-test reliably if we use the feed from our broker only. And that could only be done, if our broker provide the history data, which majority of the broker do not (at least mine does not which Investtechfx). So the choice we have is only to back test around two months data that we can find on our LIVE M1 chart. That means whatever bars we have on our M1 chart are the Bars from our Broker and our strategy behavior on these Bar can help us understand, how good or bad our strategy would perform with our broker.

To do that, we could Export M1 data to CSV format and then import it in Offline mode and test our strategy in offline mode. This would give us at least a feeling that how our strategy would perform on our Broker.

I am open for suggestion and sharing my experience on this subject.

For most accurate backtesting you should switch the wicks on and use the backtest mode switch which prevents jumping of the open price. Moreover, your indicators should use only the close price. This is the way that the backtesting will be the most accurate as it can be.

I meant: is it still a renko chart by all definitions of renko if it has wicks?

As far as I am informed a renko chart consists of bricks and not candles: http://www.investopedia.com/terms/r/renkochart.asp
This would mean to simulate it with candles you would make high/low identical with open/close to display these bricks. A wick would indicate that it "forgot" to start a new brick like the rules dictate when it exceeded the range of the brick.

Thanks Aktur, You are right, I am doing this over the week-end and I found it more near to live feed.

You have highlighted a very important point about INDICATOR close Price. This suggestion help us saving our time by eliminating those indicators in our strategy which use other than close price.

Still the test in progress. Will post here if found something interesting to share.

You are correct about Renko definition but from a price action point of view it is the opposite true. Renko definition insists that the bricks 'forget' about price action during the brick formation and cut off wicks. However, during backtesting you would like to recreate all price action as accurate as possible. This can be done only by adding wicks. Also, wicks do not cause to 'forget' to start a new brick - just look at a chart with and without wicks - all bricks start at exactly the same time and price in both versions.
