I know that market volatility is primarily driven by news, however, i am
just curious if any one could share any indicator to predict how
volatile currency can be within a particular time say 30 minutes. I have
an EA that works perfectly with grid system. the only thing is that one
cannot predict volatility. if say there is any indicator to determine
that the market will move 20 pips at a set time, the EA does not care
about the direction it must be in profit.
so my question is is there anything like volatility predictor indicator for trading forex.
Average True Range is the basic one. Not predictive but you can find volatility at that time. Lagging is disadvantage.
You can also use moving average of standard deviation but they are lagging too.
More advanced one is called GARCH or ARCH. GARCH is preferred in general over ARCH. This one is predictive one.
Difficult to write into code properly but not impossible. Used by many practitioners.
