Technical Analysis -Part 1
RSI- Relative Strength Index
· It is one of the most effective and most
used technical tool of stock market developed by J. Welles Wilder Jr. and introduced in his seminal 1978 book, "New Concepts in Technical
Trading Systems."
· It is classified as momentum indicator because it measures
the velocity and magnitude of price movements. It helps
to analyze the strength and weakness of stock
or market based on the closing
prices of recent trading periods.
· It has a measurable scale from 0 to 100. There
are some default level marked on
this scale like 30 and 70 as low and high level which can be changed
by the user according to their use and perception.
·
By default it has 14 days time frame which again can be changed by the user as per
their convenience.
·
Traditionally it is said that the
security above 70 and below 30 are
in overbought and oversold zone which
is true but at the same time it should not be interpreted that if RSI is 70 or
70+ one has to sell that script as soon as possible because it is in overbought
zone. Whenever such condition occurs one should be cautious toward his/her security
and should place strict stop loss which can be the low of last price candle or
technically it can be determined by the help of ATR (Average True Ratio) and
most important investor should consider his risk appetite by himself because he
is investing his own hard earned money in a highly volatile and speculative
market. Similarly when RSI 30 is obtained it cannot be said that stock is fully
oversold and had made bottom now it is time to buy, it can further go down till
0( 0 is almost impossible but it may go to that point also)
Mathematical Formula = 100-100/(1+RS)
· Where, RS = Average Gain / Average Loss
Some
General levels/Methods which I observed and learned from my Gurus and markets
which I can suggest in this article are as
·
Divide the RSI scale in 0-20, 20-40, 40-60, 60-80, 80-90.
·
Now these division can be used
effectively with uptrend and downtrend
of stock and market like
·
If market/stock(which ever you
are analyzing market or stock) is in uptrend
and RSI is in between 0-20 it is a strong buy or if trend is downtrend and RSI is 0-20 one should wait for uptrend. Short selling should be avoided in this
zone because it is highly risky zone for shorting, reversal can be seen at any point.
·
If market/stock is in uptrend and RSI is in between 20-40
then again it is in buy zone or if trend is down trend then it will be in a
sell zone with strict stop loss.
·
If market/stock is in uptrend and RSI is in between 40-60
then again it is a buy(high) zone or if trend is downtrend in the same zone
then it is a sell condition.
·
If market/stock
is in uptrend and RSI is in between
60-80 then it will a buy zone with high momentum but if there is a downtrend
momentum then it is a highly sell indication.
Some
spot levels
·
RSI at 20 with Uptrend – Strong
buy
·
RSI at 40 with Uptrend – Strong
buy
·
RSI at 60 with Uptrend – Strong
buy
·
RSI at 80 – Cautious zone
– selling can be done ( stock momentum should be
considered because some stock may fall from 80 or some 85 or some 90 on the
basis of their momentum but at RSI 80 selling zone start)
·
RSI 90( rarely seen) – Strong
sell.
·
Similarly when trend
is downtrend
·
RSI at 20 cautious
·
RSI at 40 – Strong sell
·
RSI at 60– Strong sell
If RSI makes ‘U’ turn
at RSI 20,40,60 then it is strong buy.
