Dear developers, how do you get rid of Warnings in this situation?

How about this:

template <typename T>
T GetValue()
{
  T Res = NULL;
  
  return(Res);
}

and if you do it like this:

it would be a bummer.

MT5 1578 - always crashes.

MT5 1571 and MT4 1065 - works without any problems. Crash script herehttps://www.mql5.com/ru/code/16280

1580 - OK.

MT5 loses MT4 on time of access to data by 6-10 times!

MT5 loses MT4 in terms of data access time by a factor of 6-10?!

It's not - I checked.

fxsaber:

EA for the tester (Metaquotes-Demo)

Result

Limit sliding on the exchange symbol - BAG!

Slippage of the limit order in the exchange market is normal:

Suppose the current market is 114300 / 114280

You place a buy limit order of 114250. Someone in the market has decided to sell at a guaranteed price (not worse than the price specified in the order) and set a sell limit of 114200. As a result, all buy limit orders in the range from the market to 114200 have been collected.

This is quite normal in the stock market.

Brought our discussion (for convenience)here.

Thanks. i checked on two computers and wine 1.6 and 2.4. now i checked on win xp, no difference between mt4 and mt5.

Can anyone suggest a solution to the Copy functions...

There are no bars inside auctions on MOEX stock section, but Copy functions... These time ranges are included as bars, i.e. if we order one-hour bars for several days, the time-series array will include bars 09:00:00. I don't want to take chunks of time-series and then splice them together, maybe there is another solution?
