(1) is not the last candle. (0) is the last candle.

Look at the price when the candle ends. The candles must end at exactly the same time on both platforms and the Close price must be exactly the same.

I think your problem is your actually checking 2 bars back, use priceOpen(0), priceClose(0) etc etc....to check the last candle.

Ok, this means zorro do not consider current candle. These are the differences with mt4 that lead me into a traps. I worked about 10 years with mt3/mt4.

however, I get almost the same differencies about what zorro reads and what Trading Station tells:

function run()
{
BarPeriod = 30;

printf("\n\nOpen = %.5f", priceOpen(0));
printf("\n\nClose = %.5f", priceClose(0));
printf("\n\nHigh = %.5f", priceHigh(0));
printf("\n\nLow = %.5f", priceLow(0));
}

Zorro:

Open = 1.30668
Close = 1.30649
High = 1.30675
Low = 1.30633

Trading Station:

Open = 1.30592
Close = 1.30627
High = 1.30651
Low = 1.30550

Sorry, but I don't understand why these are differencies!!!

does anyone have any idea about?

For excluding a different time offset, can you do the same test with M1 candles?

Test with the M1 candle:

function run()
{
BarPeriod = 1;

printf("\n\nOpen = %.5f", priceOpen(0));
printf("\n\nClose = %.5f", priceClose(0));
printf("\n\nHigh = %.5f", priceHigh(0));
printf("\n\nLow = %.5f", priceLow(0));
}

Zorro:

Open = 1.30761
Close = 1.30774
High = 1.30794
Low = 1.30761

Trading Station:

Open = 1.30743
Close = 1.30755
High = 1.30774
Low = 1.30742

Ok, I will now look into this myself. I don't have the Trading Station installed here, but I'll set it up and check what's happening.

I have tested it also on a demo account with the same results.

Ok, I've just tested it and can not confirm the problem. I installed Trading Station and opened a m1 chart. The last full candle that I see - before the partial candle that is just building - has the same OHLC values that were printed by Zorro.

Maybe you were looking at the Bid instead of the Ask prices?

Do you have a difference between the price in Zorro's server window, before the blinking asterisk, and the current price in Trading Station?

You are right, I realized my mistake. Sorry, but I never traded with Trading Station before and MetaTrader is more user friendly but I have a feeling that zorro is more powerful and effective.

Thank you very much for your support.
