Automating the Stock Market Fundamentals
^^^^^^^^^^^^^^^^^^^^^^^^^^^ ------------
You can write scripts to perform automatic and algorithmic trading on the Stock Market. The Stock Market is not as simple as "buy at price X and sell at price Y". The following
See :ref:`netscript_tixapi` for more details. are several fundamental concepts you need to understand about the stock market.
.. note:: For those that have experience with finance/trading/investing, please be aware
that the game's stock market does not function exactly like it does in the real
world. So these concepts below should seem similar, but won't be exactly the same.

.. _gameplay_stock_market_spread:
Spread (Bid Price & Ask Price)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The **bid price** is the maximum price at which someone will buy a stock on the
stock market.
The **ask price** is the minimum price that a seller is willing to receive for a stock
on the stock market
The ask price will always be higher than the bid price (This is because if a seller
is willing to receive less than the bid price, that transaction is guaranteed to
happen). The difference between the bid and ask price is known as the **spread**.
A stock's "price" will be the average of the bid and ask price.
The bid and ask price are important because these are the prices at which a
transaction actually occurs. If you purchase a stock in the long position, the cost
of your purchase depends on that stock's ask price. If you then try to sell that
stock (still in the long position), the price at which you sell is the stock's
bid price. Note that this is reversed for a short position. Purchasing a stock
in the short position will occur at the stock's bid price, and selling a stock
in the short position will occur at the stock's ask price.
.. _gameplay_stock_spread_price_movement:
Transactions Influencing Stock Price
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Buying or selling a large number of shares of a stock will influence that stock's price.
Buying a stock in the long position will cause that stock's price to
increase. Selling a stock in the long position will cause the stock's price to decrease.
The reverse occurs for the short position. The effect of this depends on how many shares
are being transacted. More shares will have a bigger effect on the stock price. If
only a small number of shares are being transacted, the stock price may not be affected.
Note that this "influencing" of the stock price **can happen in the middle of a transaction**.
For example, assume you are selling 1m shares of a stock. That stock's bid price
is currently $100. However, selling 100k shares of the stock causes its price to drop
by 1%. This means that for your transaction of 1m shares, the first 100k shares will be
sold at $100. Then the next 100k shares will be sold at $99. Then the next 100k shares will
be sold at $98.01, and so on.
This is an important concept to keep in mind if you are trying to purchase/sell a
large number of shares, as **it can negatively affect your profits**.
