1. 3 stages of Trading Life CycleSurvival – Learn to survive in the market. Trading is never easy, if you have to pay for your mistakes, make sure it is an affordable mistake and that it will not wipe you out of the game. Trading is a lifelong game. Money is your oxygen, if you lose it; you are out of the game.Profits – Once you can survive in the market, you will notice you have the ability to make small profits from time to time. Reinvest and see how your account grows in this stage.Massive Profits – This final stage comes when you can take bigger positions in the market. As your trading account grew in the “Profits” stage, you will be able to take position of bigger size and hence your profits will be more. Also, this is when you will be able to spot and sit on big runners consistently.Passing through each stage requires patience. If you are to

Forum posts are a way to connect with other marketers and just as in offline business, networking is what online marketing is all about. When people get to know you, they trust you and this may spark them to buy your product or join the program you’re promoting. And, it’s always a great way to make new friends.The first thing you must do after joining is to introduce yourself to the other members of the group. Usually, this will include information about where you live, what your interests are, and a blurb about being happy to be in the forum. Keep it simple and allow veteran members to welcome you. Then, respond to their comments or questions. It’s a great way to get your feet wet and to satisfy the “getting to know you” requirement of most forums.Then, just read posts for a while. Old-timers in a forum, those who have been members a while, can often be great sources

Arguments are often passed to (VBScript) scripts in a set order. The writer of the script perforce has to assume that the user of the script will supply ALL of the available Arguments in the correct order. We can improve upon the way Arguments are passed to scripts by using switches within our Argument line.
The benefits of passing switches are:
- Arguments can be passed in any order.
- Non-essential Arguments can be left out.
- We can be confident in testing certain Arguments pass particular criteria.
- There is clarity within the actual Argument line being passed making it easier to read and understand.
As an illustrative example let's create the beginning of a script that's purpose is to search a file for particular words and write results out to the Command Line Interface (CLI). Our Arguments will be:
- File name.
- Switch [/W[W1,W2,W3...Wn]]: List of words to search for.
- Switch [/C]: A count of the number of times we find the passed in words.
- Switch [/U]: To return a unique list of words found.
The absence of a switch for the filename will notify our script that the Argument is a filename.
Arguments passed to a script are held within the wscript.Arguments object. To access these Arguments we need to first instantiate an Arguments object:
dim command_line_args
set command_line_args = wscript.Arguments
We can now process the Arguments passed to our script. Let's call our script SearchLight.vbs and assume that the following Arguments are passed:
SearchLight.vbs /U /W boat,green,sailing BoatSales.csv
Our script's purpose is to return a unique list of green sailing boat names from BoatSales.csv. We start by iterating through the Arguments passed and capturing the criteria. Though the Arguments object is an object with a Count method, we retrieve its Arguments starting at zero: Like an array. We'll make reading the code easier by adding a Constant called FIRST_ITEM, which is set to zero, and a Variable called LAST_ITEM which will capture the index number of the last Argument held by our instantiated Arguments object.
const FIRST_ITEM=0
dim LAST_ITEM
dim args_index
dim command_line_args
set command_line_args = wscript.Arguments
'Check if any Arguments have been passed to our script.
if command_line_args.count > 0 then
LAST_ITEM = command_line_args.count - 1
for args_index = FIRST_ITEM to LAST_ITEM
next
end if

Small business loans for women involve a number of procedures. Firstly, they have to submit the loan application that seeks comprehensive information about the project. Specifically, the application form covers aspects like promoter’s background, particulars of the industrial concern, and particulars of the project (capacity, process, technical arrangements, management location, land and buildings, plant and machinery, raw materials, labor and schedule of implementation).In addition, the loan application form seeks the cost of the project, means of financing, marketing and selling arrangements, profitability and cash flow and economic considerations. When the application is received, an officer of the recipient institution reviews it to ascertain whether it is complete for processing. If it is incomplete the borrower is asked to provide the required additional information. W

Getting a home equity loan, or second mortgage, for the sole intent of consolidating and ultimately eliminating unnecessary debts is a great plan. Many consumers are burdened with high credit card balances, consumer loans, etc. Reducing or paying off debts takes time. Furthermore, many do not have the disposable income to lessen credit card balances.Owning a home places you at a huge advantage. Those who have built equity in their homes may acquire a home equity loan as a way to reduce debts. These loans are affordable, and serve a useful purpose. However, debt consolidation home equity loans have certain risks.How Do Debt Consolidation Home Equity Loans Work?The concept of debt consolidation home equity loans is simple. Home equity loans are approved based on your home’s equity. A home’s equity can be calculated by subtracting the amou

When the first Kingdom Hearts video game came out in 2002 on the Sony PlayStation, quite a few people wondered if the folks at Square-Enix had gone out of their minds. A role-playing game showcasing sunny Disney characters along with the angst-ridden figures of the company's Final Fantasy games? The idea seemed cheesy at the time. However, Kingdom Hearts as well as Kingdom Hearts: Chain of Memories (released on the Game Boy Advance) were runaway hits, appealing to both young and older gamers in the East and West. Now, with the release of Kingdom Hearts II, PS2 players can continue to explore old and new magical worlds with familiar and endearing characters.It's not necessary for a person to have played the previous installments of the game to enjoy Kingdom Hearts II, but it would be helpful. The adorable Sora is still the main character (although you'll start the game a

There are many kinds of insurance policies existing in Chicago, but Chicago personal injury liability insurance is among the most accepted, since it costs less than other choices.For instance, with respect to auto insurance policies, liability insurance charges cost much less than complete coverage. This is because complete coverage has to pay for one’s vehicle as well as some other vehicle concerned in a mishap, as well as property costs and medical expenses resulting injuries to the owner or a different party.Chicago personal injury liability insurance only applies to the additional party's damages. An individual and his property are unshielded, but liability insurance shelters a person from being held accountable for the other party's losses. There are diverse categories of liability insurance, together with general liability, which operates to a great extent in t

select case (command_line_args(args_index))
case "/C"
'User only wants to return a count of the number of boat names found.
count_only = true
case "/U"
'User wants a unique list of boat names found.
unique_name_listing = true
case "/W"
'Boat names must belong to boat records matching these criteria.
'Increment our Arguments counter by one to capture the next Argument with is a list of words.
args_index = args_index + 1
'Split the word list by the comma delimiter returning an Array of words to search for.
criteria = split(command_line_args(args_index),",")

'assume a file name passed.
file_name = command_line_args(args_index)
end select
The most interesting Argument is the one that provides a list of words to search for. The "/W" switch alerts our script that a list of words is to follow and therefore we increment the Arguments index by one to capture that list. The next interesting Argument is the "/C" Argument because it wasn't passed. When an Argument fails to match any of the conditions listed in our Select Case statement our program assumes that it is a filename. It is the only assumption available so it can be confidently acted upon.
Our full script looks like below:
const FIRST_ITEM=0 dim LAST_ITEM dim args_index dim count_only: count_only=false 'Default of false instantiates variable dim unique_name_listing: unique_name_listing=false 'Default of false instantiates variable dim criteria dim file_name dim command_line_args set command_line_args = wscript.Arguments
'Check if any Arguments have been passed to our script. if command_line_args.count > 0 then
LAST_ITEM = command_line_args.count - 1
for args_index = FIRST_ITEM to LAST_ITEM
select case (command_line_args(args_index))
case "/C"
'User only wants to return a count of the number of boat names found.
count_only = true
case "/U"
'User wants a unique list of boat names found.
