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.

Wedge-Wedge

 Wedge Bull Wedge


In an uptrend, a trader may see a bearish or bullish wedge. Unlike triangles, wedges do not have a flat side. Both sides are tilted in the same direction.


With a bullish (descending) wedge, local lows are updated. At the same time, the price in the range slows down. Therefore, on a rising chart, a bullish wedge looks like a small correction. The highs and lows of the wedge are approaching. Typically, traders open short positions after breaking through the upper boundary of the bullish wedge.


bearish wedge

A bearish (rising) wedge forms similarly to a bullish one. The difference is that local maxima are updated. The price in the decreasing range is slowing down. With a bearish wedge, a trend reversal or a subsequent correction is possible.
