Whats definition of spread for BAR s (as compared to tick spread) Spread at any tick Ask - Bid.

Ask and Bid can change each tick, and bars are accumulations of ticks.

Now that Im answering my own threads, hope it clears it up for others wondering what returns what.:) Thats incorrect information.

The only problem is its not well documented, so people are trying to use it with MT4.

On Metaquotes world, the spread is always related to Ask-Bid, never to high-low or whatever.

Actually it was the maximum in the past, but changed to minimum, I dont remember when.

Right now in my MT5 terminal (build 1881), spread value of each bar is the max tick spread found in that bar.

So CopySpread and CopyRates return minimum spread in bar, and DataWindow shows max spread of bar:).

However its not coherent, checking current D1 and lower timeframe I can see its the minimum.

Bug or feature Its weird logic to consider the minimum spread occurrence of a bar.

What possible use could one have for that Checking D1 and lower TF of different brokers on my terminal shows that it is not the minimum spread but something else.

What possible use could one have for that Actually, i hoped to see minimum spreads of bar.

Apparently on higher timeframe, which on MT5 are build from M1 data, its the maximum of M1 bars of the considered timeframe candle.
