Do market makers go against a client's position? By definition, a market maker is the counterpart to all its clients' positions, and always offers a two-sided quote (two rates: BUY and SELL).

If the RSI is 70 or greater, then the instrument is assumed to be overbought (a situation in which prices have risen more than market expectations).

Many profitable trades are made moments prior to, or shortly after, major economic announcements.
