Renko and Matlab

  • #1
  • First Post: Jul 8, 2010 7:08am Jul 8, 2010 7:08am
Just wanted to put this out there in case anyone else would like to collaborate down different avenues. I'm trying to incorporate this with a neural network, maybe co-integration, and possibly trend spotting / reversal, and/or a combo of all.

Anyway, here are a few charts of GBPJPY with different sized Renko boxes -> i used the fib #'s for lack of better imagination :/

They're made in Matlab. I couldn't find any code or syntax to describe Renko, so Andrea182 (user on this forum with whom i am trying to corroborate) suggested using Renko to filter out noise. So i made my own.

Do you trade this method?

No, I do not trade it. I did look at Renko charts awhile back, but didn't like all the fancy footwork of having to set them up on "offline charts" as I could never figure out how to do that.

All this was is taking GBPJPY daily data from MT4 and adding the formula that says if the next price is more than x points from today's price, record the new price, otherwise, ignore it and move onto the next price.

My next step is to use this as an input for a neural network.

Hi
Something doesn't seem to be right. Look at the daily chart of GJ in MT4. Even with 55 pip renko bars the price is never that smooth. I could be wrong. It would help if you could post the Matlab logic.

You're right, that is 1 unit of the currency, so 1 Yen, 2, Yens, 3, 5, 8, etc..

I'd be glad to change it to pips if that would serve some purpose.

1 yen = 100 pips in GY (assuming two digit broker). So the 55 yens you are using is actually 5500 pips. At such large pips daily data may be sufficient to construct Renko but practical use may be limited.

If you move to lowers pip range like 10, 20, 50.. it's best to use one minute data and run the attached EA to generate an offline chart in MT4. You can then open the offline chart and save the data as CSV in MT4 itself.

One last thing is, in recent years Support Vector Machines have become more popular than Neural Networks. Something to consider. LIBSVM has great Matlab and Python bindings to play with.

Its smooth becaue renko is plotting the past history and on the daily its not showing the full intra-day, hour, 30mins, 15min etc up and down.
Just the final daily bar.

Renko should only be on 1min chart. Putting it live on any TF other then 1min will look just like the 1min TF.
If you put it on any other TF leave it running for a while.........renko will plot the live price up and down, but once you open and close the chart the history will be repainted to be more smoother and wont mean much....looks good though

Thanks for your input and the indi yesbee. What is your experience with SVM, have you had success with it?

Are you conversant with Matlab, do you use it for trading?

Haven't used SVM for trading. Not conversant with MATLAB. Too many projects right now, but SVM is something I will look into in the next couple of months and will let you know if I am able to come up with something.

Those Renko charts showing BS.. Some of those Renko indies

will just draw straight lines up or down for the history, nothing to do with reality..

They are fake.. They will only show true picture ones they placed on the chart and forward..

Just straight ups and downs , if this

was true, we all be millionaires overnight..

I don't care what you say about me, but if

you think this chart is real, - keep dreaming..

Box size 55? You want to tell me that from Jul 2007 till DEC 2008 (1.5 YEAR PERIOD!!!) there was not a single

day when GBPJPY rebound more than 110 pips in different direction? Are you serious???


Trade it and comeback

to testify, when you completely broke

I'm telling you those Renko Indies are completely screwed.. They are working somewhat ok forward,

but you need commercial copy, if you want to get real charts.. Not those bogus Pyramid looking Renkos..

This his how a 55 Pips Renko looks like based on M1 Data starting May 2010 GBPJPY.

Exactly.
I was very surprised to read that a 55-pip Renko block correlates to 550 pips. I wonder where such unbelievable bullshit comes from.

Easy. Everyone makes a mistake or two once in a while.

Now here's 550 Pips that not even 83 Renkos with M1 Data back from 1999.

That's good to know. The fact that I trade profitably with renko everyday is obviously an illusion.

Can we have a look at your 550 pip Renko on weekly?

Are you a coder? I'll be willing to share my matlab code with you to confirm that we're on the same page.

Right now, i have my Renko outputs as inputs into a system of feed-forward-back-propagation neural networks to forecast the next weekly close.

Not to sound like someone who has bought into the proverbial snake oil, but the capture shows that the NN forecasted a higher close for this week 143.29 vs. 141.2 for last week.

My goal is to collaborate with willing folks who have constructive interests in developing a sound MM. This system is better than a coin flip, so with good MM, it has a lot of potential.

Since it is based off weekly, it should be easier to partner up since time zone differences, time constraints, etc should not be a problem.

Also, i should note i chose weekly b/c daily is touchy, with Mondays and Fridays being discretionary trading days and news events having ripples into the next day etc..

From the saying, "garbage in = garbage out" I deduced that weekly would be more accurate than daily.

If anyone has CONSTRUCTIVE words, be it criticism or not, that would be great.
