Previous tick's value

Remember the price for the last tick,  compare it to the price of the current tick . . .  if(Bid - LastTickPrice) > 0 price has gone up

Straightforward. Just wanted to make sure there is no inherent data structure for this that I am ommitting. Btw Raprtor, how do you do that that you always come first to respond and almost within minutes ...?:-)

I am at one of my PCs most of the day . . .  I keep an active eye on the Forum.  Answering questions where I can helps me expand my knowledge . . .

int start(){
   static double tickCurrent; double tickPrevious = tickCurrent; tickCurrent = Bid;
   :
   if (tickCurrent > tickPrevious) ... // Up

Thanks guys.:-)

I am so sorry to bring such an old topic back to the surface but I need to know if it is possible to store more than 1 tick "in the memory". 

I would like to have the ability to know the price for:

Current tick
last tick
tick before last tick

and actually more if it is possible.

Thanks in advance :) 

use array or for everything you want to keep an extra variable.

Thanks! Please give me an example of storing the last 5 ticks (prices)

You cannot get recent ticks in MQL4, you have to remember them. Or you may move to MQL5, they have a rather fresh function for it : https://www.mql5.com/en/docs/series/copyticks 

So, it is possible to see last tick and the current tick but no more? Strange...
