Average True Range

This indicator of volatility measures selling pressure and buying pressure. When the ATR rises there is more and more pressure and a strong volatility of the stock.
When the ATR decreases there is less and less pressure and a low volatility.
True range is the highest data in absolute value among:
(Today’s high - today's low)
(Today’s high - yesterday's close)
(Today’s low - yesterday's close)

The last two possibilities usually arise when the previous close is greater than the current high (signaling a potential gap down or limit move) or the previous close is lower than the current low (signaling a potential gap up or limit move).
To ensure positive numbers, absolute values were applied to differences.
True Range is the greatest of the following three values:
• Difference between the current maximum and minimum (high and low).
• Difference between the previous closing price and the current maximum.
• Difference between the previous closing price and the current minimum.

Bears power

Bears Power oscillator developed by Alexander Elder & it based on estimation of bears Power balance since changes in this balance initially signalize about possible trend reversal.
There is always a war between the bears (Pushing prices down) & bulls (Pushing prices up) that depend on the demand& supply in the market & at end of each day there is a result of this war (high or low prices) so during the day it’s very important to be able to estimate the reverse of the line chart.
If trend indicator is up-directed and the Bears Power index is below zero, but growing, it is a signal to buy.

Moving Average Convergence Divergence (MACD)

This indicator was generated by Gerald Appel as the difference between two exponentially smoothed averages (EMA).
It’s one of the simplest and most reliable indicators available.
Although there are three moving averages mentioned you will only see two lines one fast and one slow, if the faster signal line crosses above the slower line then a buy signal is generated and vice versa.
There are three techniques commonly used to interpret the MACD:
1) Crossovers, When the MACD falls below the Signal line, it is a bearish signal indicating that it may be time to sell.
2) Conversely, when the MACD rises above the Signal line, the indicator gives a bullish signal, suggesting that the price of the security is likely to experience upward momentum.
3) Divergence, when the security price moves counter to the MACD it signals the end of the current trend.
4) Zero Line Crossover, A crossing of the MACD line up through zero (the centerline) is interpreted as bullish, or down through zero as bearish. Some analysts choose to buy or sell when the MACD goes above or below zero.

Bar Chart:

Is a chart with rectangular bars of lengths usually proportional to the magnitudes or frequencies of what they represent.
Uses bars to show frequencies or values for different categories, also known as a bar graph. 
Bar charts are used for comparing two or more values. The bars can be horizontally or vertically oriented.
Sometimes a stretched graphic is used instead of a solid bar.
Each bar contains 4 'hooks' (the opening, closing, high and low (OCHL) rates of transactions at a certain time interval).

Momentum

It measures the amount of change in commodity’s price during a period of time.
Momentum indicators presume that the current tendency will continue. So, if the indicator reaches the extremely high values and then turns downwards, the coming price increasing should be expected. But, in any case, one should not open/close position before the prices confirm the signal of the indicator.
Momentum line goes long when:
Momentum crosses to below the oversold level and then rises back above it; or on bullish divergences - where the first trough is below the oversold level.
Momentum line goes short when:
Momentum crosses to above the overbought level and then falls back below it; or on a bearish divergence with the first peak above the overbought level.

Line Chart:

Is a two-dimensional scatter plot of ordered observations where the observations are connected following their order.
The line chart is a graphical representation of the historical exchange rate of a specific currency pair in a certain period of time. The line is brought into existence and drew according to the closing prices connection of the day.
