Charting

[ancien...@gmail.com]

Are there any plans to add charting capability to the code base? Do others use external display engines to give candle stick displays etc?

Hello,

No, we want to keep the codebase cleaner and with the basic framework functionalities.

Charting capability should be done separatley in order to avoid any performance impact on the engine functionalities.

Personally I store every candle event into a DB ( not necessary the tbg-Quant DB ) and then I do some basic charting from there (with a PHP webapp). You can also store moving average data, entry and exit signal, etc...

hope this helps

bye

Hello Josh,

For legal reasons we cannot share the code of tbg-QuantDesk.

Anyway, i can give you some suggestions:

1) tbg-Quant by defautl use an in-memory DB, if you want to use PHP to connect to that DB you need to switch from in-memory to persistence DB.

Edit youir tbg-Quant.config file and change the default setting.

2) Then, run your TBG, it will store persistence data in your DB

3) tbg-Quant default DB is H2. Check out this page to connect with PHP using the odbc driver.  http://www.h2database.com/html/advanced.html#odbc_driver

4) tbg-QuantDesk  is using Jetty server with this configuration that works like a charm

<?xml version="1.0"?>

<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure.dtd">

<Configure class="org.eclipse.jetty.webapp.WebAppContext">

    <New id="database" class="org.eclipse.jetty.plus.jndi.Resource">

        <Arg>java:comp/env/jdbc/database</Arg>

        <Arg>

            <New class="org.apache.commons.dbcp.BasicDataSource">

<!-- ## H2 DB ## -->

<Set name="url">jdbc:h2:C:/Temp/test/tbg-quant/data/tbgdb;AUTO_SERVER=TRUE;MODE=MYSQL</Set>

<!-- ## MySQL ## -->

<!--<Set name="url">jdbc:mysql://localhost:3306/test</Set>-->

<Set name="username">sa</Set>

<Set name="password"/>

            </New>

        </Arg>

    </New>

</Configure>

5) Once you connected to the DB, you can basically access to every table, use the H2 client to browse around and get the idea.

6) Use a flotcharts to plot : http://www.flotcharts.org/

    Check their website with many examples of real time graphs.

7) everythings shoulb be mixed up with HTML :-)

Hope this helps,

bye

Isn't there a better way to use the DB for building candles with java and using an open source charting class like - http://www.jzy3d.org/documentation.php
