My basic finding is if there is a change in MarketInfo() for the pair, a "tick" is received.
There may be exceptions, like "no changes found" but a tick was received, but it is very rare.
Ticks received with no price change are not rare, and signal some other change in MarketInfo for the pair.
Volume is equal to the number of ticks received, i.e. the number of times the start() function was called, it is not specifically trades or Bid/Ask changes. Change in MarketInfo()triggers a tick, and tick count = volume.
if I think well :
1 Tick = 1 PIP
Have I the right?
1 Tick = 1 Pip or more .... Pip/ Second
The term tick is used loosely to describe an event, and the lowest possible change in price.
As an event; tick == the arrival of a new price quote
As a monetary value it is the lowest possible change in price; tick == Point.
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()
Is there a point to answering a 6 year old question ? or are you just trying to mess up the thread listing ?
if I think well :
The Forum Admin already answered correctly, did you read the thread ?
I have encountered another problem.
Book says TICKVALUE is in deposit currency.
However, practice shows some brokers return the value in other currency than the deposit currency.
Moreover, I have seen cases where ie. one CFD's TICKVALUE was in deposit currency, while another's was in base currency.
This ruins programming completely.
Anybody knows where the broker sets this up?
C/z it seems complaints to the broker don't always bring effect, so they should be educated.
