Bollinger bands breakout Indicator For MT5

Bollinger bands breakout Indicator For MT5

Bollinger bands breakout Indicator For MT5 fungerer på en meget enkel idé. Først og fremmest oprettes båndene ved hjælp af simpel beregning af glidende gennemsnit sammen med standardafvigelsen. Ved nøje at lægge mærke til prisoversigten, vil du bemærke små markeringer i øverste og nederste bånd, når prisen falder.

Markedet udføres, når prisen lukker over Bollinger-båndet. Men de erhvervsdrivende skal nøje vælge tidsrammen baseret på markedsvolatilitet, da meget afhænger af det. For eksempel, hvis volatiliteten er højere, er det bydende nødvendigt at stole på den større tidsramme som D1 eller den ugentlige.

Tværtimod, når volatiliteten ophører, er de erhvervsdrivende nødt til at se på de mindre tidsrammer. Men brugeren af den mindre tidsramme skal stole på prishandlingssignalerne. Medmindre de gør det, vil de håndtere for mange falske signaler. Og vær altid opmærksom på de vigtigste nyhedsdata, da den største opdeling sker på sådanne kritiske økonomiske begivenheder.
