It can be used in any market, any time frame .
For conditions we have multiple conditions for the logic, in this case initially if our fisher is above 0 is a long direction ,if its belowe 0 its a short direction.
Also we can improve this condition even further, in this case if we cross up our previous line its a buy signal, and if we cross down its a sell signal.
For best usage combine the cross together with the position of fisher respecting the 0.
