Exponential moving average and how to calculate EMA

Exponential Moving Average (EMA)
 Exponential moving average or EMA is also known as exponentially weighted moving average (EWMA). It gives more weight to recent prices in other words the weight of old prices decreases exponentially.
 A seven day EMA applies 25 per cent weighting Calculation of EMA is a complicated one. Stock market traders can get EMA from almost all technical charts.
In order to calculate EMA, first calculate SMA.
SMA = Mean or average of previous n days= Sum of n days / n
For eg, 7 SMA= Sum of Seven days closing price / 7
Then you have to find smoothing factor.
Smoothing factor = (2 / (Time periods + 1) ) = (2 / (7 + 1) ) = 0.25 (25 per cent weighting; ie 0.25*100)
Then calculate EMA by applying the following formula.

EMA= [Close - EMA(Yesterday)] x Smoothing Factor + EMA(Yesterday).

Note that Some people use current price instead of close.

If you know the per cent and want to get time period you can use the following formula.

Time period= (2/Smoothing Factor)-1
Here smoothing factor is per cent divided by 100.
For eg;- If the per cent is 25, smoothing factor is 25/100= 0.25
Then time period= (2/0.25)-1= 7; so seven is the time period.

An example of EMA calculation on a sheet is given below

Day	Close	7 SMA	Smoothing Factor	EMA 7
1	87.50
2	86.00
3	85.00
4	86.20

28	94.50	92.67	0.2500	92.94
29	94.80	92.90	0.2500	93.41

EMA 5, 10, 20, 50, 100, and 200 are very common in stock market trading

What is Simple moving average: How to calculate SMA

As the name indicates Simple moving average (SMA) is the simplest form of all the moving averages. It is the unweighted mean of the previous 'n' data points.
 In stock market SMA is simply calculated by taking the mean (average) of a security over a specified number of days. One can calculate moving averages from open, high, low or close prices. But in most cases, close prices are used to calculate SMA.
 If you want to calculate a seven day simple moving average of a security, add the previous seven day closing prices and divide it by seven (mean or average of last seven days). You can't calculate simple moving average if you don't have last seven days closing price.
 An example of a seven day moving average is given below
 

Day	Close	7 Day SMA
1	58
2	64
3	62
4	60
5	63
6	65
7	65	62.43
8	67	63.71
9	68	64.29
10	67	65.00
11	66	65.86
12	64	66.00
13	65	66.00
14	67	66.29
15	69	66.57
16	70	66.86
17	67	66.86
18	65	66.71
19	62	66.43
20	63	66.14
21	66	66.00
22	68	65.86
23	71	66.00
24	69	66.29
25	70	67.00

 You can also calculate simple moving average of 'n' days using the following formula.

 Suppose  previous 'n' day closing prices are 

 Then Simple moving average



In order to calculate simple moving average in a row (for successive values) use the following formula

  

For short term trading most people use 5, 10, 20 and 50 SMA. For long term 100, 200 SMA's are considered as important.

Book value per equity and book value per share; its importance

 In accountancy 'book value' is the value of an asset as per balance sheet. It is also called carrying value or net asset value, which is equal to the original cost of the asset less any accumulated depreciation, amortization or impairment costs made against the asset.
 In share market traders use book value to determine the safety level of shares after the payment of all debts.
 Total Book value of an equity is the value that the equity worth after the repayment of all debts and liquidation of all assets.
 Total Book value of equity is calculated by the following formula,
 Total Book value of an equity= Book value of assets- Book value of liabilities

 Book value of all Common shares is calculated as
 Book Value of Equity- Book Value of Preferred Stocks

Book value per share is defined as the value, that share worth after repaying all debts and liquidating all its assets.
  Book value per Common share is calculated by using the following formula
 Book Value per Common Share = (Total stock holder's equity- Preferred Equity)/(Total Number of outstanding Shares)

Market order and Limit order in stock markets

In stock markets, trades occurs when orders are placed. When one trader places buy order and another trader places sell order at the same price trade occurs.
 One can place buy order or sell order in order to enter or exit the trade in stock markets. If some body enters to trade by placing a buy order he can exit from that trade by placing a sell order. If some one enters to a trade by placing a sell order he can exit from that trade by placing a buy order.

Market order

Market order is an order placed with a brokerage to buy or sell shares in the current market place. In market order trader tells the number of shares he or she want to buy or sell. Market order will be executed immediately. If you place a market order to get some shares of a company you will get the shares at a price somewhere between the ask and bid price. In high volume markets, market orders are comparatively safe. Market order guarantee the execution subjected to the liquidity of that scrip, but does not guarantee the price.
 For example a security is trading at 500 RS and you place an order for 100 shares, 100 shares of that security would be bought for you at the price of 500 RS per share.

Limit Order

Limit order is a conditional order, which can be defined as the order placed to buy when the market price of the stock comes to the limit price you set. Limit orders are some times classified as buy limit orders and sell limit orders. Limit order guarantee the price, but does not guarantee the execution.

For example if you place an order for 100 shares of a security at 500 RS, which is trading at 550 RS, your order would be executed when the price come down to 500 RS.

Buy Limit Order

If you think that the price of a security will decrease in short term and then rebound to a higher price you can place an order to buy the security at lower levels.
For example A security is trading at 100 RS. If you think the price of that security will decline to 80 RS, you can place a buy order at RS 80. Only if the price come down to 80 RS, your trade will be executed.

Sell Limit Order

If you own a security, and think the price will go higher in short term. Then you can place a sell order at a higher price. If the price reaches that higher level your limit order will be executed.
For example A security is trading at 100 RS. If you think the price of that security will increase to 120 RS, you can place a sell order at RS 120. Only if the price go higher to 120 RS, your trade will be executed.
