Hello everybody. I only had performance issues with NINJA once, and that was from having too many (+18) windows open with Market Profile, Cumulative Delta Order Flow. and on several instruments at the same time. My computer is relatively powerful (ryzen 7, 32 Gb RAM) so it is something that can happen and can cause serious performance problems. All this was aggravated by not having some indicators well configured. It is important that the moving averages, if you are going to use many simultaneous charts, are configured to be calculated at the close of candles. If you make rational use of your hardware, you shouldn't have any problems.
I know this is a late response...
I use tick(100 and 300) and minute(1, 5, 15, 30, 60) charts. I trade using the Super DOM not off the actual charts though (I have chart trader on but hidden on some charts so I can see my positions and orders). My trades always seem instantaneous. For day trading I usually trade es. So tons of liquidity in case it was the bid/ask spread that was part of the problem.
I do have a lot of charts open and I often have two trading platforms open as I use NT for day trading, but I use TWS for managing my portfolios. My computer is 6 core with 16Gb ram and running on an SSD, but it is older so no power house. I have two video cards and 6 monitors, so I always have a lot running. I can tell when I'm pushing it by the sound of the fans as they ramp up to max.
I have also big problem with lagging on NT8 with ninjatrader brokerage and data feed from ninjatrader server... Also I can guarantee how bad is servers on ninjatrader particulary. Could be their slogan before sell their product. I installed an addon to measure lagging on data. I have an average of 500-700ms all the day. I tried all and when I tell all is all... Isn't my computer isn't my Ethernet connexion isn't my system... Is only problem of NT. I can certify that because I connected to test on same platform same system Interactive broker connexion through API and as a miracle I have only 5-10ms on same markets same templates same platform...
It couldn't be worst.
from 30 to 50 secs to send, change or cancel order. During fast market, NT really sucks. Sometimes it takes 2 minutes to get confirmation. And NT gives no response on this issue. I love NT but Tradestation is another planet.
What about having a stop loss , that for NT is client based? You get the point :-(
There's definitely something going on with the latest version of NT8. I was working on the simulator this week, not trading live. Three days in a row a couple of NQ and ES trades had huge slippage - I mean huge!
Below is a jpg of one of the trades. Contacted NT8 support - they asked for detailed information which I sent. Not sure what to think. Can you imagine if this was a live trade?????????? It was a huge loss.
Something screwy with NT8.
I might transfer my account to Tradeovate for a while and only use NT8 for my order flow indicators.
I've seen something similar on NT8 but that was explicable. In my case it was in a thinner market (MCL) and just before the inventory report release where it took 20 or so seconds to fill a market order. Yours makes no sense. I checked yahoo charts and they show a run up to your stop price but it's like 4 minutes later. At least I think I'm looking at the right time, 2:33 pm eastern? I suspect that it's an issue with the data service and the simulator is based on that. Had you had a live order in with the exchange, it would have likely not have stopped you out there. Just my guess.
I'm hoping you're right. It happened several days in a row on the NQ and the ES. The support gurus are looking at it. I did a replay today, executing the trades at exactly the same time - no problem there. That leads me to believe it was some type of anomaly that occurred on the platform at those particular times. Otherwise, the replay data download would have reflected the extreme slippage.
Another anomaly yesterday was that the log, where you would expect to see an error message, started recording over an hour into the session. So I think it's something screwy with the platform.
The question remains, however, about live trading. And that could be a catastrophe.
