The maximum trade size on SGT Market’s MetaTrader 4 platform is a volume of 50.0 lots or 5 million notional trading units in FX. The MT4 platform has limitations that are designed to prevent it from incorporating partial fills, and this is why there is a maximum trading limit to help reduce the number of rejections when placing larger orders. Please contact us if you would like to trade larger position sizes and we will be pleased to assist you.
