It's much simpler than that.

Why do you need a KillCount variable when you can just put tickCount%100

"find the difference".

int KillCount=tickCount%100;
if (KillCount == 0)

if ( tickCount%100 == 0 )

so the same thing)

"find the difference."

He needs a variable that resets at every hundred.

I already wrote there "if" isn't needed at all, just

int KillCount=tickCount%100;

What might be the secret meaning of such a design?

int OnInit()
  {
  ........

   OnTick();

   return(INIT_SUCCEEDED);
  }//OnInit


void OnTick()
  {
.....
}

Where did you find this?

Maybe the author wanted to execute OnTick() during initialization

Valeriy Yastremskiy #:

What could be the secret meaning of such a construct, tell me.

To run OnTick logic immediately at load (restart), without waiting for a new tick. It makes sense on inactive pairs, although it's better to remove it in the timer.

There must be IsConnected, TradeAllowed and similar checks

There are checks). But isn't the first OnTick after OnInit called on tick arrival and not forced?

I'll have a look at the print on Saturday. It's just that my EA is drawing. And it also draws at the weekend, I think. I'll have to check it out.

No tick - no OnTick(), even on first run.

There are cases when graph objects are drawn in OnTick, but if there is no tick, it will not draw anything. That's why we made a single call to OnInit.
