Renko Block Charts

Hello,
here is my problem: sometimes I have a serious delay when I send orders.
That happens because cpu-usage is at 100% and everything is like frozen.
That is because with every new tick every indicator is calculated from the start of its history.

1.How can I reduce the history to a period that makes sence
(my eurusd 1-min chart begins April 2010) ?
5 days would be enough....

2.How do I have to change the code in order to calculate an indicator...
1. Go to Options/Charts and reduce the Bars In History number.

2. Attach the indicator in question - someone will help you...

I am trying to use your code and test an idea but the close value for the BarTradeE only resolves to 4 digits ie on gbpusd 1.610 so when comparing bars this willl be a problem as i beieve 1.61080 will be read the same as 1.61055 a difference of 3 pips or worse can the array read 5 digit or at least 4 digits after decimal point ie .6108

If you have renko bars set to 10 am i correct that a new bar will be opened once 10 pips have been travelled either up or down and a new block added ie price is 1.6000 price goes to 1.6010 and new bull block added price drops to 1.6000 and bear block added - I am a little confussed as why the wicks surly each block is 10 (or whatever you set it at)

Is this not the whole point in so far as the blocks are fixed pip sizes and not related to time ie a 100 pip movement may take a day or 2 days but could be rfepresented by 10 blocks assuming move is continual up trend or sown trend

Hope someone can help

thanks, reducing the bars really worked great, no more cpu-problems (still using tick by tick calculated indis)


the indis I would like to have with a calculation only once per bar are attached - maybe its possible to build in a input switch to change from once per bar to permanent recalculation.

if someone could do this for 1 or 2 of these indicators - great !
(I will try to do it with the rest, and , if it works, post them here)

After thinking this through on a 10 pip block the maximum drawdown is 20 + cost of trade is this correct

The indicators (or at least the one I looked at) are already calculating correctly. After the initial startup during which all bars are processed, only the current bar will be calculated.

I know and have corresponded with IgorAD - he's an excellent coder and would not post indicators that do not function correctly.

I am one of the worst coders on earth, I didnt even see that only the last bar is calculated.
Let me explain the problem once again taking FLATTREND as an example:
during the actual bar/brick sometimes I receive more then one alert.
starts with BLUE, then RED, then BLUE again. sometimes the alert sound makes pling pling pling every 5 seconds. I want to have an alert/buy-sell-signal only once and only if it doesnt change any more and that is in the moment a new bar starts.

That's a separate problem. There are several ways to make an alert show only once per bar but the right way depends on how the indicator is coded.

Generally, you can just use a "lastAlertTime" data item and set it to bar time when the alert is sent. Then don't send any more alerts until current bar time is greater than "lastAlertTime".

when using barcharts taking the open(appears only once) instead of the close(constantly changing) should do the job.
is that right?
when using renko the open is not fixed until the next brick starts. I would have to use close[1] instead of the actual open. right?

lastAlertTime will work well with barcharts, but will it work with renko?

Right.

See previous answer. If you're trying to find when a new block starts, compare Open[0] to Close[1]

lastAlertTime will work well with barcharts, but will it work with renko?

Sure - renko blocks have open time same as any chart.

thank you very much, I didnīt know lastAlertTime refers to the open, I thought it is just the time of the last alert

"lastAlertTime" is not a part of mt4 - just a name I suggested for a datetime data element. All you want to do is prevent an alert being sent with each new tick - you can either use time or a simple switch that is reset on each new bar...

Have fun.

Is this indicator what you are looking for? It sounds a single alert each time a completed renko bar changes color.

Thats a nice indicator and Iīm using it with the bigger bricks,
but I was talking about the signals of for example the macd on a 2-pip-brick chart.
Iīll try to post an example of an re-coded indi later today.

Hi all, I'm using the expert version 3.2.

Is there the possibility to open multiple charts of the same cross, with different sizes?

For instance, I need to open 2 EUR_USD charts with 10 and 50 size.
I tried to open two 1 MIN charts, I indicated different timeframes (M2 for 10 block size and M3 for 50 block size) but it doesn't work.

Thank you!

  • Apr 6, 2011 4:25am Apr 6, 2011 4:25am
You have to open one chart for every renkochart you want to see.
And you have to give everyone a different name - you cannot use m2 for all of them. Donīt use 1,5,15,30,60 and so on.
I have 3 different eurusd-charts (2/5/10-pip) running realtime - no problem.

It works perfectly - I just tried it. Be sure that you are using a separate M1 for each Renko and that RenkoTimeFrame is 2 for one Renko chart and 3 for the other.

Attached two Indicators, one can use them to see the picture of Renko on different pip-box.

Hope it helps

hows it going marley,

do you ever try the metatraders profiles for running multiple block size for each pair?

its under "files/profiles" in metatrader, you can save a profile for different renko block size and have a profile for each pair, it works good.
