Help understanding Tester Journal

[Alberto]

Hello,

I'm new to trading, but with years of experience in programming.

However, I can't understand some messages I get in journal.

I got the code for the new bar from https://www.mql5.com/en/articles/159

Here's the code I'm testing, a simple EMA crossing script:

#include <Trade\Trade.mqh>

#define _SLOW 100
#define _FAST 50

CTrade trade;
int maSlowHandler;
int maFastHandler;
long lastTime=0;
//+------------------------------------------------------------------+
//|                                                                  |
//+------------------------------------------------------------------+
void CloseAllPositions()
  {
   while(PositionsTotal()>0)
     {
      trade.PositionClose(PositionGetTicket(0));
     }
  }
//+------------------------------------------------------------------+
//|                                                                  |
//+------------------------------------------------------------------+
bool isNewBar()
  {
   long lastbarTime=SeriesInfoInteger(_Symbol,_Period,SERIES_LASTBAR_DATE);
   if(lastTime==0)
     {
      lastTime=lastbarTime;
      return(false);
     }
   if(lastTime!=lastbarTime)
     {
      lastTime=lastbarTime;
      return(true);
     }
   return(false);
  }
//+------------------------------------------------------------------+
//|                                                                  |
//+------------------------------------------------------------------+
int OnInit()
  {
   PrintFormat("OnInit: %s",TimeToString(TimeCurrent(),TIME_SECONDS));
   maSlowHandler=iMA(_Symbol,_Period,_SLOW,0,MODE_EMA,PRICE_CLOSE);
   maFastHandler=iMA(_Symbol,_Period,_FAST,0,MODE_EMA,PRICE_CLOSE);
   return(INIT_SUCCEEDED);
  }
//+------------------------------------------------------------------+
//|                                                                  |
//+------------------------------------------------------------------+
void OnDeinit(const int reason)
  {
   PrintFormat("OnDeinit: %s",TimeToString(TimeCurrent(),TIME_SECONDS));
  }
//+------------------------------------------------------------------+
//|                                                                  |
//+------------------------------------------------------------------+
void OnTick()
  {
   double maSlow[3];
   double maFast[3];

   CopyBuffer(maSlowHandler,0,0,3,maSlow);
   CopyBuffer(maFastHandler,0,0,3,maFast);

   if(isNewBar())
     {
      if(PositionsTotal()>0 && maFast[1]<maSlow[1])
        {
         PrintFormat("CLOSE: maFast[1] < maSlow[1] (%.7f < %.7f)",maFast[1],maSlow[1]);
         CloseAllPositions();
        }
      if(PositionsTotal()==0 && maFast[0]<maSlow[0] && maFast[1]>maSlow[1])
        {
         PrintFormat("BUY: maFast[0] < maSlow[0] (%.7f < %.7f) && maFast[1] > maSlow[1] (%.7f > %.7f)",maFast[0],maSlow[0],maFast[1],maSlow[1]);
         trade.Buy(0.01,_Symbol,0.0,0.0,0.0,NULL);
        }
     }
  }
//+------------------------------------------------------------------+

And here are some screenshots of the tester:

Settings: 

1: 

2: 

3: 

And here are my questions:

Picture 1, why is there a autotrade #6 -> #7 on the 4th of january 8am, but journal doesn't show anything for that time?

Picture 1, why is it trading at 8am when the lines are clearly not crossing?

Picture 2: why is it saying that's autotrade #5, when the journal is saying deal 5 takes place the 11th of january?

Picture 2: why is it showing 3 lines going out of autotrade 5, that go close at 3 different times?

Picture 3: what is it doing here? it opens and closes multiple times evend though my conditions are so simple, only do trade on crossing ma.

I know I must be doing something wrong, I'm not blaming mt5.. I just need some help understanding.

Thanks
