Any good open-source trading platforms for futures and stocks?

you can customize it any way you want. No limits.

 

correct. If you need this large amount of charts, it will not work. I am not aware of any software that can handle it.

 

The issue is the number of securities in the database - of course you can't have them all open! Amibroker handles that number of securities just fine for charting.

For backtesting Realtest is super-quick - just got it recently but only using it for daily data, AmiBroker is also quite quick.

Ninjatrader can't handle thousands of securities at all - it crashes (I forget the limit) but made it useless for portfolio backtesting of stocks. It does work well on FX though.

Choose the tool to suit the task.

 

I've always wondered if that had to do with the way NT processes tick data, and how it trashes spinny drives.

Has anyone tried this on a pure SSD system with NT8?

 

You are limited by the way they have designed their software. For example you can't easily replace the broker layer.

 

Agree on this one. But at the same time not so hard. Establish multiple connections and this give you option to pick and choose which broker to use.

 

I have the life-time multi-broker license of NinjaTrader. But the more I use it, the less I like it.

 

we do not need 1000s of symbols on the same machine and it works great. NT7 had backtest issue due to single core, NT8 just rocks.

 

This is reason all of our servers are upgraded with NVMe SSDs and have a noticeable performance boost.

 

yes, it's definitely faster. SSD is too cheap to not upgrade nowadays
