Of course you can. Start studying MQL5.

Create an array and then in the OnTick() function check each tick if the price has changed, comparing the current price with the price in the first [0] element of the array. If it is different, then shift all values starting from the last one to the neighboring ones and place the current price in the first element of the array. Repeat this every tick.

Start writing the code yourself. When you fail and have questions - ask.

I got it, but I can't figure out what function is used to move values within the array. I understand that each tick should be compared with the existing one, but how to move them - that's the main question.

This is not clear!

This one is not clear!

For example, ArrayCopy- you copy from array A[] to the intermediate array B[], then you return it back to array A[], but shift it by one and only write the new price value to array A[], to the first cell (A[0]).

Pr[4]=Pr[3];
Pr[3]=Pr[2];
Pr[2]=Pr[1];
Pr[1]=Pr[0];
Pr[0]=SymbolInfoDouble(_Symbol,SYMBOL_BID);
 
vicmos:
so only the first value is filled in with the index [0].
