Oracle

 Oracle Database is a database management system from Oracle. This DBMS is also actively used by large companies and costs a lot of money, but in return it provides great functionality and reliability. Therefore, Oracle Database and Microsoft SQL Server are serious competitors to each other. The results of Oracle in the rankings are not so clear, for example, according to PYPL and DB-Engines, Oracle Database ranks first, according to Stack Overflow Oracle is in eighth position, according to surveys of Oracle software companies in fourth place in popularity. If we take into account only a couple of ratings, Oracle can even be put in first place, but if we take into account all the results, then Oracle cannot be put in first place, therefore, in our rating, this DBMS occupies the third line.

MACD indicator (Moving Average Convergence/Divergence)




 The MACD indicator is one of the most popular oscillators, developed by renowned trader and analyst Gerald Appel. "Moving Average Convergence/Divergence (MACD)" translates as "convergence and divergence of moving averages". As the name implies, MACD uses a combination of several movings with different parameters.


The indicator is calculated in a separate window on the terminal screen and consists of two lines, one of which is represented as a bar chart. The trading signal is the intersection of these two lines, as well as divergence (divergence) - the discrepancy between the extreme values ​​of the indicator (highs and lows) with the price chart. Divergence can predict an incipient correction or even a trend reversal.
