Hello there,

I'm trying to import some Renko data into WL and I'm struggling . I have the Trend Chart Styles extension installed, but somehow after importing the data, it does not reflect what I see on my trading platform where I took the data from. It shows something completely different on WL.

The data being imported is formatted as follows and it is being imported already formatted in the 6R format.

Date - Time - OHLC - Volume

07-06-2023;17:45:46;4950;4952;4947;4952;1292698635
07-06-2023;17:38:21;4947.5;4950;4946.5;4950;763908365
07-06-2023;17:04:09;4945;4947.5;4941.5;4947.5;1837722290
07-06-2023;16:22:35;4945;4949.5;4942.5;4942.5;6272196920
07-06-2023;16:21:00;4945;4947.5;4944.5;4947.5;642829560
07-06-2023;15:59:01;4942.5;4945;4940.5;4945;1949722135
07-06-2023;15:24:56;4940;4942.5;4936;4942.5;3518183715

So each line above reflects a 6R box.

Once I import the data into WL and go to charts, I select Renko and then click on the Gear to "Configure Renko". There I select:

- Based on: HighandLows
- Box Size: 6R
- Brick type: Value
- Show Wicks: Yes

What am I doing wrong, please?

Hello,

QUOTE:
already formatted in the 6R format.

The data to import by the ASCII historical provider must be in the OHLC format.

Hi Eugene, thank you for your reply.

What I'm struggling with is this, do I need to import the data in the format that I want to see on Renko? For example, do I need to import it formatted 6R if I want WL to display it only in 6R?

I'm doing this, and for some reason it's not working.

The format I'm using above is 6R with date, time, OHLC and volume.

Hi,

Like I said, you should import the raw OHLC data. WL does not support 6R or whatever for this purpose. Just pure OHLC and then you apply the Renko chart style in WL to build the virtual bars.

Hello again Eugine!

One last question pls.

When you say raw data, do you mean raw data on 5 min chart, 15 min chart, daily chart or any timeframe will do the job?

Thanks again.

Answer: the base time frame of the data. Seconds in the timestamps of your sample data suggest it may even be in Second scale.

Note that Wealth-Lab's Renko chart don't have to match your other platform's, and their algorithm is unknown to us.

Hi Eugene,

I thought Renko is Renko regardless of which platform we use. Just like 15 min is 15 min regardless of which platform we use.

I selected 6R on the platform that I use, so it created boxes of 6R each with a wick too.

The timestamp that you see is when a new box is formed. As you are aware Renko is not based on time, but on price movement.

Tbh with you, I can replicate what I see on the platform that I use in any other platform, but WL. Because of the simple fact that Renko is Renko just like 15 min is 15 min everywhere.

The fact that your last answer is like washing your hands to the question that I'm presenting, does not help and I don't know why you even bothered to reply if that's how you intended to help.

And yes, WL as a backtesting platform should and must be able to at least guide its users on how to import data from the main platforms in the market, otherwise you lose the very purpose of being a backtesting platform.

No data provider that we are aware of produces data in Renko format. WealthLab accepts data in tick or OHLC bar format and can create Renko objects from that raw data. Being the backtesting and auto-trading platform that we are, you can apply trading rules based on those Renko “bricks” and generate trading signals in real time.

What is the source of your 6R bars? Which broker will you be trading with?

Edit -
I just reviewed the data sample, and there should be no reason that you cannot import that using the ASCII provider. Create a new DataSet in the Data Manager, select the ASCII provider, point it to your data file folder, and carefully specify the format.

Hello Cone, thank you for taking the time to reply.

I'm using ProfitChart as my trading platform and as my data provider. I trade in the Brazilian stock exchange. All local brokers and trading platforms take the data from the stock exchange which is centralized, not like with Forex that you may have slight variations on the prices and data depending on the broker.

I've been using WL with the data provided by ProfitChart for a long time and I've run many simulations using regular time frames such as 2min, 5min and 15min. Never had any problems up until trying to run a simulation using Renko on WL.

With regular time frames, what I see on ProfitChart is what I see on WL, not a single issue with that.

However, if I try to use the same data of regular time frames and ask WL to make it into Renko, it doesn't match what I see on ProfitChart. If I export the data from ProfitChart already in Renko format, it also does not work.

The data that I posted above is an export in Renko format.

You cannot import data in Renko format to Wealth-Lab.

Right, so why does it not work when I import in regular format too? Why does WL does not plot the boxes as it should?

Can you pls give me an example that works? It can be any stock, futures, whatever from any platform.

Why don’t you send us your ascii file in OHLCV format to support@wealth-lab.com? We can create a DataSet and show the resulting Renko chart here and analyze it in detail to answer any questions?

Hi Glitch,

I e-mailed you on the 13th of June. E-mailed you today again with the data you requested.

Cheers,
