What is a TICK? - page 5

 
delbroooks: Is it possible to plot every tick in the indicator plot. I want to plot live ticks streaming into an indicator (irrespective of the plot period), is that possible and how?

Yes, obviously - that was one of the many points of that very comprehensive post you quoted which includes examples of code to achieve just that! Did you even bother to read it and follow the links provided?

Market Watch -> Symbol tab -> symbol -> Tick Chart tab.

No, and No.

There is Tick, PIP, and Point. They are all different in general. A tick is the smallest change of price. A Point is the least significant digit quoted. In currencies a pip is defined as 0.0001 (or for JPY 0.01)

On a 4 digit broker a point (0.0001) = pip (0.0001). [JPY 0.01 == 0.01] On a 5 digit broker a point (0.00001) = 1/10 pip (0.00010/10). Just because you quote an extra digit doesn't change the value of a pip. (0.0001 == 0.00010) EA's must adjust pips to points (for mq4.) In currencies a tick is a point. Price can change by least significant digit (1.23456 -> 1.23457)

In metals a Tick is still the smallest change but is larger than a point. If price can change from 123.25 to 123.50, you have a TickSize of 0.25 and a point of 0.01. Pip has no meaning.

This is why you don't use TickValue by itself. Only as a ratio with TickSize. See DeltaValuePerLot()
