Skew between tick time and current bar

New comment
 

Hi all,


I'm pretty new to MT4 and MQL, but I found a strange behavior on the following code:


void OnTick() {

  int order_action_status;

  MqlTick last_tick;

  SymbolInfoTick(Symbol(),last_tick);

  Print("TICK: " + TimeToString(last_tick.time, TIME_DATE|TIME_SECONDS));

}


That code produces an output like this:

2015.10.05 02:00:25.491    PAPERONE_WR_DIVERGENCE EURUSD,M1: TICK: 2015.10.05 01:00:24
2015.10.05 02:00:25.335    PAPERONE_WR_DIVERGENCE EURUSD,M1: TICK: 2015.10.05 01:00:24
2015.10.05 02:00:24.680    PAPERONE_WR_DIVERGENCE EURUSD,M1: TICK: 2015.10.05 01:00:23
2015.10.05 02:00:24.555    PAPERONE_WR_DIVERGENCE EURUSD,M1: TICK: 2015.10.05 01:00:23
2015.10.05 02:00:24.321    PAPERONE_WR_DIVERGENCE EURUSD,M1: TICK: 2015.10.05 01:00:23
2015.10.05 02:00:20.546    PAPERONE_WR_DIVERGENCE EURUSD,M1: TICK: 2015.10.05 01:00:19

2015.10.05 02:00:18.471    PAPERONE_WR_DIVERGENCE EURUSD,M1: TICK: 2015.10.05 01:00:17


The problem is that looking at the chart I can see the candle at 00:59:00 is still forming...using ticks in the future to create that candle....

What am I missing?

Are you testing in Visual mode? Then no problem.

Hi,


thank you for the quick reply, but I didn't understand it.

I'm not back-testing, the EA is attached to a real-time graph with 1minute candles; what I see is that when onTick() fires for a tick who has a time HH:MM:SS, inside the chart the candle under construction is that who has time HH:MM-2:SS

To reproduce the suspected issue it's enough to create an empty EA who has insidere the OnTick() function the following 3 lines:

MqlTick last_tick;

SymbolInfoTick(Symbol(),last_tick);

Print("TICK: " + TimeToString(last_tick.time, TIME_DATE|TIME_SECONDS));


If you attach the EA tho a graph, I'll see that the tick received and printed by the EA have a timestamp which is outside the range, related to the current candle.

For example, if in the graph the candle at 01:00 is under construction, I expect the bigger timestap of a tick should be 01:00:59 (but I see ticks with timestamp 01:01:XX)

I don't understand how it's possible


Thank you.

Regards,

Alberto

 

It sounds weird, and I never noticed anything like that. Can't that be just you did not focus properly the last bar? Switch the last bar data in your Data Panel (ctrl + d).

Sometimes (but rarely) the ticks swap (i.e. the next tick has older timestamp), but it is always within one second interval.

Hi all, please see below a screenshot to best explain what I meant; as you can see the candle at 16:41:00 is still under construction but I'm currenlty receiving thicks with timestamp 16:42:XX

It could be very useful if someone could try to run this test in his mt4 platform.

Telling us what you see isn't helpful as wed can't see it. Print your last_tick time, Time[0], and TimeCurrent() in one line so you can see all of them.

What I can see in your picture is a candle at 16:43 under construction and your output reads 16:43 as well.
