As I said before I am not going to explain this script in plain english as its already simple, this is the reason I recommend AutoIt as the best hobbyist programmer language

What about the order quantity ? - The order quantity is based on CHUNK_AMOUNT variable set in ICICI_Configs table. It will check how many units it can buy with
CHUNK_AMOUNT/OrderPrice rounded off to integer. This allows buying any stock in chunks rather than in one single go.

Ones the order placement is done it will update the YstClosingQuote value for the respective ticker/symbol. Look at ICICI_Log table screenshot in Part II to get better understanding on sequence of activities.

Part II - Trade Signal Generation

By now you know how the database is layed out. In the following parts you will be mostly dealing with AutoIt script which intracts with market data and my database with configurations and watch list.

I will put all of the source code here instead of explaining it in plain english. Since the AutoIt is BASIC like language it easy to understand.

This above code is the one which captures the ticker/stock price and writes it to the ICICI_Watchlist >> CurrentQuote column. As soon as the column is updated
with new price the trigger on that table fires up and checks if the price is
closer by the expected target price (QuoteVariance), if yes it will generate
a signal.

Is the signal buy or sell ? - this depends on QuoteVariance. If QuoteVariance
is set as minus that means you are looking for price going lower and lower, so
BUY signal is generated for PreviousClosing-(PreviousClosing*QuoteVariance)

Similarly if the you are looking to sell your holdings if price goes above +5% (QuoteVariance) of previous day closing then SELL signal is generated

In the next part, I will explain how this signal is processed and order is actual placed.

PART I - Database (Stock Trader)


I am assuming you have read the assumptions and about the requirement of this program in the start-up page.

Let me start with database design piece here in this article. We have put up 5 tables. ICICI_Configs, ICICI_WatchList, ICICI_Signal, ICIC_Log and ICICI_Holiday

Table - ICICI_Configs:

This table holds the application configurations like when to start, how long to watch the market, the user and password for the a/c to place order.

Below is the simple table structure

CREATE TABLE ICICI_Configs (
ConfigID integer primary key autoincrement,
ConfigVariableDesc varchar(500),
ConfigVariable varchar(30) not null,
ConfigValue varchar(100) not null
)

And here is the data how it looks like in my case,



Note: START_TIME and STARTED_AT variables are to be set to your local timings like i.e. if you are in India it should be set to 09:55:00, but if you are in United states its 21:25:00


Table - ICICI_WatchList:

This is where I store my stock ticker to watch (that I am interested in). With price target percentage movement values.

CREATE TABLE ICICI_WatchList (
Ticker char(6) primary key not null,
YstClosingQuote numeric (20, 4),
CurrentQuote numeric (20, 4),
QuoteVariance numeric (6, 2),
isActive bit default 0, -- if 1 collect quote for this TICKER
LocalDateTime DateTime default CURRENT_TIMESTAMP
)

Here is the how the data would look like...




Table - ICICI_Signal:

In this table I put the buy/sell signal record, whenever this is a ACTIVE signal in this table the order placement thread (program) will start its real action. Following is the table structure for the same,


CREATE TABLE ICICI_Signal (
SignalTicker varchar(10) primary key not null,
SignalPrice numeric(20, 4),
CurrentPrice numeric(20, 4),
SignalActive bit,
SignalDateTime datetime default CURRENT_TIMESTAMP,
TrnType CHAR(4)
)

Below is how the data would look like,



When there is an active record i.e. SignalActive = 1, the Order Placement theread will start logging in to ICICI Direct site and place order. While placing the order it will pick up the lower of the SignalPrice or CurrentPrice. The CurrentPrice will be continuosly updated until the Signal is marked inactive i.e. SignalActive = 1 so that while order placement happens and the Current trading price of a scrip/ticker goes down it can take advantage of that situation.


Table - ICICI_Log:

ICICI_Log is a logging table, where application writes about activity it has taken. Here is the table structure and sample data,


CREATE TABLE ICICI_Log (
Id INTEGER primary key autoincrement,
ThreadName varchar(100),
LogDesc varchar(1000),
LogDate datetime default CURRENT_TIMESTAMP
)



The above figure should tell you how the things work. Apart from logging the detail the application also captures the images/screenshot. These screenshot can be helpfull in case if there is any issue with the site.

Now let me explain how the signal generation works. ICICI_WatchList has two triggers as follows,

trg_UpdWatchList_BuySignal

CREATE TRIGGER trg_UpdWatchList_BuySignal UPDATE OF CurrentQuote ON ICICI_WatchList
WHEN (new.CurrentQuote <= (Old.YstClosingQuote+(Old.YstClosingQuote*Old.QuoteVariance))*1.005 ) and Old.isActive = 1 and Old.QuoteVariance < 0
BEGIN
INSERT OR REPLACE INTO ICICI_Signal VALUES (Old.Ticker, (Old.YstClosingQuote + (Old.YstClosingQuote*Old.QuoteVariance)), New.CurrentQuote, 1, Current_TimeStamp, 'BUY');
UPDATE ICICI_WatchList SET YstClosingQuote = (Old.YstClosingQuote + (Old.YstClosingQuote*Old.QuoteVariance)) WHERE Ticker = Old.Ticker;
INSERT INTO ICICI_Log (ThreadName, LogDesc, LogDate) values ('BUY TRIGGER', 'Updated signal value for ' || Old.Ticker || ' (' || new.CurrentQuote ||')', current_timestamp);
END

trg_UpdWatchList_SellSignal

CREATE TRIGGER trg_UpdWatchList_SellSignal UPDATE OF CurrentQuote ON ICICI_WatchList
WHEN (new.CurrentQuote >= (Old.YstClosingQuote+(Old.YstClosingQuote*Old.QuoteVariance))*0.995 ) and Old.isActive = 1 and Old.QuoteVariance > 0
BEGIN
INSERT OR REPLACE INTO ICICI_Signal VALUES (Old.Ticker, (Old.YstClosingQuote + (Old.YstClosingQuote*Old.QuoteVariance)), New.CurrentQuote, 1, Current_TimeStamp, 'SELL');
UPDATE ICICI_WatchList SET YstClosingQuote = (Old.YstClosingQuote + (Old.YstClosingQuote*Old.QuoteVariance)) WHERE Ticker = Old.Ticker;
INSERT INTO ICICI_Log (ThreadName, LogDesc, LogDate) values ('SELL TRIGGER', 'Updated signal value for ' || Old.Ticker || ' (' || new.CurrentQuote ||')', current_timestamp);
END


If you look at the trigger very closely you will see that when the trading price is +/- 0.5% range the signal is generated, this is because I wanted to ensure that the order does not get rejected due to out of range pricing.

This is all about database side implementation, let check what is there in AutoIt scripting side in Part II - Market Watch

My little stock trader.


This one is my latest and favourite little program out of my hobby programming. And is about stock trading specific to INDIAN market and the stock broker is ICICI Direct in this case. Technical requirements - Windows OS, Internet Explorer 6 (and above), AutoIt and SQLite.

What is it after all ? - this is a little program that I wrote to do stock trading. When I wrote this program the requirements were I wanted someone to watch the market (specific stocks about 10 tickers) and buy/sell based on price movement. Eg. if Infosys technologies stock is up by 7% want to sell out my holding in Infosys OR assume that I want to hold more stocks of Bharti Airtel but only if it goes below by 7%. Currently you can specify the target prices in +/- percentage only.

This simple thing can be done by placing limit orders isn't ? - NO, not atleast in ICICI Direct. You cannot place limt orders beyound +/- 5%, even during the market hrs. If you are with other stock brokers may be you have a choice.

This program uses Autoit - my obvious choice for hobby programming (atleast for now) and SQLite - combination of these is too great. Earlier I never thought I could write such good/powerfull program using these two piece of softwares, but indeed it worked out well - thanks to AutoIt and it support for SQLite, plus their incredibly simple documentation with good working samples.

This program is also a great sample application for learning AutoIt and SQLite :)

For the simplicity I have split this article into 3 sections as follows,

Automated Trading - interesting

I have an account with folioinvesting (earlier known as foliofn). They have a system of window trading i.e. you can place your order during that window trading period and those trades are less expensive - refer to their site for more. But I wanted to place window orders at 8 am and 11 am. There are many times when I am office or in transit so I used to miss it. Also automation makes the timing more accurate. Then I decided to automate it, so wrote this script. This script demonstrates (apart from logging in) clicking of links, selecting radio buttons and clicking on specified images. When I say clicking not just clicking randomly here and there, but to accomplish this task of placing an window order. To place a window order in foliofn it takes about 10 mouse clicks and going through 3-4 screens, more than that its the timing that is important. So, I wrote this script and scheduled it - problem solved. It also generates the log as well.I have added some customizations to suite my requirements


Currently this script places orders blindly, I mean it runs at scheduled time and places the order, the scope of improvement is - it should be intelligent enough to decide whether to place or not or when to place 8 AM or 11 AM or both ?? -- I am working on it :)

How to navigate through a web page and fetch data ?

Have you ever done clicking and moving mouse across 2-3 pages just to get one small piece of information. Now with on click you can browse through multiple pages and get the piece of info that you are looking for. Here, in this example I'll show you how to get the exchange rate of INR/USD and save that value into an txt file. This is for education purpose only. Stripping data from others website may be violation of law and in some cases frequent automated browsing migh bring down the site as well.

Automating mailcity (web mail) login.


Here is my sample code for automated opening of webmail account login.




#include <IE.au3>
#include <String.au3>
#include <array.au3>
#Include <Date.au3>
#include "myFunctions.au3"


$oIE = fnOpenURL("http://mail.lycos.com", "3000")

$oFrames = _IEFrameGetCollection ($oIE)
$oFrame = _IEFrameGetCollection ($oIE, 0)
$oElement = _IEGetObjById($oFrame, "m_U")
_IEFormElementSetValue ($oElement, "your id goes here")
$oElement = _IEGetObjById($oFrame, "m_P")
_IEFormElementSetValue ($oElement, "password here")

$oElement = _IEGetObjById($oFrame, "login")
_IEAction ($oElement, "click")
_IELoadWait ($oIE)

Generic Web User Interface Login Automation


This script works for most of web login screens like hotmail.com, mail.yahoo.com, gmail.com etc. It picks up most of the configuration values from associated ini file, in this case it depends on "myfile.ini". If you want to automate loging in to other sites like comcast, AT & T you just add another section in the INI file with detail of the web UI objects


Contents of AutoIt script




#Include <Date.au3>
#include <IE.au3>


$varSec = IniReadSectionNames("myfile.ini")


If @error Then
MsgBox(4096, "", "Error occurred, You have not set the INI file.")
Else
For $i = 1 To $varSec[0]


WriteToLogFile ("Logged in user name " & @UserName)
WriteToLogFile ("Opening " & $varSec[$i] & " page.")
ShellExecute("C:\Program Files\Internet Explorer\IEXPLORE.EXE", "about:blank")
Sleep (3000)
$oIE = _IEAttach ("about:blank", "url")
Sleep (2000)
_IENavigate ($oIE, fnGetKeyValue($varSec[$i], "url"))
_IELoadWait ($oIE)
$oForm = _IEFormGetObjByName ($oIE, fnGetKeyValue($varSec[$i], "form"))
$oElement = _IEGetObjById($oIE, fnGetKeyValue($varSec[$i], "uInput"))
_IEFormElementSetValue ($oElement, fnGetKeyValue($varSec[$i], "uid"))
$oElement = _IEGetObjById($oIE, fnGetKeyValue($varSec[$i], "pInput"))
_IEFormElementSetValue ($oElement, fnGetKeyValue($varSec[$i], "pwd"))


if fnGetKeyValue($varSec[$i], "btn") <> "" Then
$oElement = _IEGetObjById($oIE, fnGetKeyValue($varSec[$i], "btn"))
_IEAction ($oElement, "click")
Else
_IEFormSubmit ($oForm)
EndIf


_IELoadWait ($oIE)
WriteToLogFile ("Signed in to " & $varSec[$i] & ".")
_IELoadWait ($oIE)
WriteToLogFile ("Inbox opened for " & $varSec[$i] & ".")
WriteToLogFile ("---------------------------------------------------")


Next


EndIf

EndIf
Next
