Sometimes during volatile stock movements the level 2 freezes on my platform for a few seconds. I cannot figure out what causes this. I contacted my broker and they always say there is no lag on their part. My specs are. i5 650 3.33ghz (Benchmark is only in the 3100's.) 4 gb ram Broker: TradeZero (Zeropro platform) Software tools I use: Trade ideas, tradingview, benzinga pro, stocktwits. What do you think is the problem and what do you recommend I upgrade? Buying a completely new PC is out of my budget atm. Do you think I can get away with just upgrading the ram to just 8gb? Any advice would be appreciated.
