It is used lớn identify potential reversal points or correction, as well as evaluation of «confidence» of the market dynamics.

What is Relative sầu Strength Index?

Relative sầu Strength Index indicator uses positive sầu (U) và negative (D) price changes in the calculation. Calculation algorithm (for standard version) is as follows:

First we determine the type of price change:

positive − current (today) closing price, higher than n periods ago (yesterday):U = Close(today) – Closе(yesterday), D = 0negative sầu − current (today) closing prices, higher than n periods ago (yesterday)D = Close(yesterday) – Cthua (today), U = 0If the prices U & D are not equal lớn zero, then the values of U & D are smoothed using EMA, as a result, «relative sầu strength» (RS) is defined:RS = (EMAof N)/(EMAof D)

Second stage: calculate final value of RSI:

RSI = 100 – (100/(1+RS))

In some sources, a simple moving average (SMA) is recommended for calculation, but do not forget that initially the indicator was developed for stoông chồng market (less volatile), & for Forex, exponential smoothing is considered optimal.

Forex Relative Strength Index is located in a separate window below price chart và represents a curve sầu with a range of values (0-100). In addition lớn color scheme, main parameter is number of bars khổng lồ calculate (author recommended value of period 14) và type of price (usually Close).

Of the many options, most comtháng are 9-and 25-period RSIs. The shorter RSI calculation period, the more sensitive sầu indicator lớn current price changes. The smaller timeframe, the longer calculation period, for example, RSI (9) or RSI (14) is recommended for daily chart, for H1 − RSI (5) or RSI (7).

In the indicator window horizontal levels are additionally used: balance − 50 & overbought/oversold − 70/30 or 80/20 (very rarely − 60/40).

You can use the 5% rule: determine (visually) màn chơi so that RSI remains behind it for 5% of total trading time for a fairly long period. For example, if you want to analyze use of RSI signals on timeframe D1, then you need lớn evaluate data for 3 months.

Relative Strength Index trading

It is always necessary to lớn remember what is relative strength index (RSI) − it is a typical oscillator, therefore its signals in critical areas are considered optimal: above màn chơi 70 (80) − overbought zone, below 30 (20) − oversold zone. Some analysts advise taking inkhổng lồ account levels 30 và 70 only in flat, và đôi mươi & 80 − on a confident trkết thúc.

So, the main signals of RSI

Determine the state of overbought/oversold. We open a giảm giá khuyến mãi for sale when the indicator"s graph leaves overbought area (above level 70), from oversold area (below 30) − lớn buy. You can also use other values of levels depending on current trend: 80/40 with a svào trkết thúc & 60/20 for a quieter market. Signal for closing a position is a turn from the opposite critical zone: for example, when the RSI overbought zone is reached, cthảm bại positions lớn buy or move sầu StopLoss cấp độ closer.

Breakdown of line of balance (level 50). Breakdown from below up – the transaction on purchase, from top khổng lồ down − for sale. Works only at trkết thúc sites, during the flat periods the bulk of signals will be false. On svào trends price is often consolidated at this màn chơi. If you look for confirmation of a bull trover, then RSI has to lớn move higher than 50. If you assume that the market will fall – be convinced that RSI is lower than 50.

Divergence. Such situations meet rather seldom, but are considered as the strongest signals of a turn. However, if range between maxima and minima of divergence on graphics of RSI is less than 7 or more 50 periods, it isn"t recommended lớn open transactions.

We remind: excess by the indicator of levels 30 & 70 doesn"t say that it is necessary lớn open the transaction immediately. The market can be in a critical zone long enough, and RSI warns about change of a trend, but doesn"t report when it occurs.

Strategy with use of the indicator

Most often, the Relative sầu Strength Index Forex is used for a scalping during the periods of rather wide flat not khổng lồ miss the beginning of the strong movement and at the same time to earn on small transactions.

The classical graphic analysis quite well works at the line of Relative-Strength-Index, for example, chạy thử of trover lines – the oscillator will warn you about possible breakdown for 3-5 bars prior lớn this sự kiện.

Except levels và trkết thúc lines, on graphics of RSI graphic models of the technical analysis, such as «Head Shoulders», «Triangles», «Top/bottom», «Flags» và other also often analyze. Relative Strength Index (RSI) often shows even those classical patterns which on the price schedule are visually not visible.

Most of traders uses Relative Strength Index indicator only in a traditional manner, but simple addition of moving average khổng lồ the line of indicator improves effect of smoothing & does signals on an entrance by more reliable. Besides, the moving average can act as resistance level for the indicator.

Several practical notes

During the unstable market trust lớn RSI signals considerably decreases. RSI (Relative sầu Strength Index) is the effective filter of current state of the market and perfectly works as the basic oscillator in complex trade strategy.

We remind: RSI is also inherent traditional delay và its signals it is necessary to confirm, for example, with signals of RSI of the senior period or trend tools, such as moving averages.
