· I came across the RSI-2 system that Larry Connors developed. Larry has become famous for his technical indicators, (12) for radiohitzfm.tk The RSI 2 Trading Strategy has been shown to produce some very good results on stocks and other markets but is that performance sustainable?radiohitzfm.tk
Sure enough, indicators use past price movements to build their indicator value; much like a moving average. Well, while indicators will never be perfectly predictive of future price movements — they can certainly help traders build an approach based on probabilities in an effort to get what they want out of the market. In this article, we are going to discuss one of the more popular indicators in Technical Analysis: The Relative Strength Index is going to measure price changes over the past X periods with X being the input that you can enter into the indicator.
If you set RSI of 5 periods, it will measure the strength of this candles price movement against the previous 4 for a total of the last 5 periods. If you use RSI at 55 periods, you will be measuring this candles strength or weakness to the last 54 periods. The picture below will show 2 RSI indicators: The top RSI is set with 5 periods, and the bottom at 55 periods.
Notice how much more erratic the 5 periods RSI is compared to the 55 periods. This is because the indicator is changing so much faster due to the fewer inputs used to calculate its value. As an oscillator, RSI will read a value between one and , and will tell us how strong or weak price has been over the observed number of periods.
If RSI is reading above 70, then price action has been strong, and price may potentially be over-bought. Because the indicator can show potentially over-bought or over-sold conditions, traders will often take this a step further to look for potential price reversals.
The most basic usage of RSI is looking to buy when price crosses up and over the 30 level, with the thought that price may be moving out of oversold territory with buying strength as price was previously taken too low. The picture below will illustrate further: Inherently, the Relative Strength Index presents a flaw to traders attempting to employ the basic usage of the indicator.
RSI, by its nature, looks for reversals in price. If the market is ranging, this can be a desirable trait in an indicator, as traders can often look to initiate entries in a range with RSI. However, if the market is ranging, the results can be unfavorable as price continues moving in the trending direction, leaving traders that had opened trades in the opposite direction in a compromised position.
The picture below will illustrate this situation further: As you can see in the above graphic, price was trending up very heavily when four different RSI sell triggers occurred all circled in red. Despite the fact that these sell triggers took place, price continued trending higher. If traders had opened short positions with these triggers, they would be in the precarious position of managing a losing trade.
Perhaps more troubling is the fact that some traders may not be using stops on their trading positions, and the trader looking to sell an over-bought market because RSI had moved below 70, may find significant trading losses as the strength that originally caused the indicator to read above 70 continues to carry prices higher. When trading with RSI, risk management is of the upmost importance — as trends can develop from ranges, and prices can move against the trader for an extended period of time.

This means the indicator looks back 14 bars on whatever graph you may be viewing, to create its reading.
Even though 14 is the defaulted setting that may not make it the best setting for your trading. Normally short - term traders use a smaller period, such as a nine period RSI, to replicate shorter term movements in the market. L onger - term traders may opt for a higher period, such as a 25 period RSI , for another indicator line.
In our final comparison, you can see in the graph below a nine period RSI line side by side with a 25 period RSI line. While there may not seem like much difference at first glance, pay close attention to the center line along with crossovers of the 70 and 30 values.
As the name implies, RSI is simply measuring relative strength of the underlying market. When using RSI to identify reversals it is important to incorporate other tools like candlestick analysis or trend line analysis. For example, if you find are reading a reversal candlestick near a trend line while RSI is diverging, then you have a trading signal being generated.
Since RSI measures the relative strength of the underlying market, it is a technical tool that can be applied to nearly any market. However, it is commonly applied to the more liquid and larger markets like forex, stocks, and commodities.
