tickCurrent > tickPrevious

[Ian Macmillan]

I am trying to create an EA that opens a buy order when the price moves up one tick and a sell order when the price moves one tick down.

 

 double tickCurrent; double tickPrevious = tickCurrent; tickCurrent = Bid;

if (tickCurrent > tickPrevious)

 

This is what I have but it doesn't work.

tickCurrent has no previous value because it's not static.
