What PC Component has the Greatest Performance impact on MT4

CPU, or Perhaps the ram? What based off of your experience plays a bigger role in the performance of MT4
Currently I use a 6 core AMD Phenom overclocked to 3.5GHz, but have noticed when running ~12 charts there is considerable delay between switching charts, scroll, and using menus. RAM is at 8GBs.

Am being unreasonable running this many charts on my current PC setup? What are your thoughts?

The resources needed aren't related on the number of opened charts ... but on what is applied on them. Some custom indicators are heavy on resources ...

you can have the best computer of the world when hooked to a inferior internet connection. my MT4 lags a bit time to time, but I am sure not because the computer, but because my net out on the sticks.
I believe your computer is more then enough to run everything you need to trade.
there is always, always another trade!!

I am using a Intel Core i7-4820K with 32 GB Ram and even there is MT slow, when i apply heavy stuff like Ferru wrote.. what i found out is, that MT4 doesn´t allow more usage than 1 GB Ram, a good and helpful solution is to reduce under options - the candle history to 512.

reducing bars just makes mt4 use less ram, but it still lags if u have more charts with more indicators, as said internet connection speed matters.

Hey guys, the issue must been associated with the amount of history I had, previously set to 500,000, now set to 512 this significantly improved the speed. My internet connection is decent but not amazing as I'm sure some Pro-traders must use. The amount of indicators (unnecessary) has been reduced which also made an improvement.

thanks for the Replies guys

also try to clear your logs from time to time, it can also improve your performance by little.

The resources needed aren't related on the number of opened charts ... but on what is applied on them. Some custom indicators are heavy on resources ...
Have always wanted to ask this: what parts of an indicator would be resource-heavy? Functions that (needlessly or not) re-calculate on every tick? Screen redraws?

(question directed not just at FerruFX but to other coders as well...)
I'm not trying to convince anyone. I'm not in the "convincing" business.

You can see my PC spec, OS and MT4 version from the attached screenshot, which also shows that MT4 is currently using 2.2GB of RAM.

I’m running ADSL2, and internet is not a bottleneck for me. The numbers in the red box show the KB download/upload since MT4 was last restarted. My understanding is that all that’s downloaded from the br0ker is the live price data, and up-to-date order P/L; and that the price data for each pair/timeframe is stored (and when necessary, recalled) from files created in the history folder on your hard drive. In this regard, MT4 is very efficient in its use of internet bandwidth, compared to other charting/trading platforms. Obviously the more different pairs/timeframes you have open (or if data from other pairs/timeframes is needed by EAs/indicators), the greater the traffic.

If you scroll back through charts, MT4 retrieves OHLC candle data either from RAM, or your hard drive. Hence, maintaining a large back history, or specifying a high number of ‘max bars in history’ or ‘max bars in chart’, should not necessitate internet use, after the data has been retrieved once. If you’re experiencing a lot of disk traffic, installing MT4 on a SSD drive would likely cause a significant speed increase; however, high disk I/O is unlikely, as MT4 seems to store a lot of price data in RAM, and only writes to history files when MT4 is exited. If you crash out of MT4, and the data does not get written, then obviously it must be re-retrieved from the br0ker’s servers.

All number crunching takes place locally; obviously the lower spec CPU, and/or the more complex indicators/EAs you have attached, the slower it will be. I don’t have any info on how effectively the latest versions of MT4 use multiple CPUs, assuming that you have them.

Easy to improve ur MT4 perfomance from the Sluggishness ,which is not related to System perfomance(Speed) like RAM capacity ( DDR3) & Processor Speed,even though if u use MT4 in Super Computer also its slow in day by day,simply using these method,which i followed for last 6yrs.

MT4 select >Tools Button > select Option > Click Charts >reduced the MAX Bars In History Box to 40000 >Max Bars in Charts Box to 3000 > log off the MT4 > Login to MT4

another way to speedup your MT4 in the attached file,if u try both methods u will get the better speed.


Try it,Best Of Luck !
