hi there. i paper trade uk stocks using ig markets. i'm using 3min charts and i'v noticed that the volume on 3min bars is sometimes quite low . let's say lloyds. it's high volume stock but sometimes there is only 5, 10 ,15k volume on 3min bars. does it mean i will have problems selling or buying shares worth 10k GBP. this is the size i want to trade all the time. what is considered as big size? and how is it with executions of mining stocks (xta, kaz ) ? hope someone can clear it for me cheers
