Delete Cache at Startup

[QuantKey_Bruce]

Would it be possible to have an optional capability to have NinjaTrader clear out the db -> Cache folder every time it starts up? I realize it could be done with a batch file but having it built into the platform would improve reliability for many users.

There are bugs in the handling of disk cache such that, for instance, at rollover, disk cache stores already built bars of the expiration before the rollover, and then when you do the rollover, it still reloads the old expiration's bars, causing discrepancies versus a machine that did not have cached data before the rollover, or that rolled over at a different time. Additionally, disk cache gets corrupted under various circumstances (many of which seem to have to do with custom bar types), such that the only way to have higher reliability is to clear out the cache before restarting.

Thank you for considering this.

Also, regarding this, I realize how tempting it might be to kick the can down the road by saying, "give us more information on the bugs so we can track them down" instead of implementing a clearing feature. And sure, that's a worthy goal. But, these bugs have existed for longer than one decade, and I think it's vanishingly unlikely they'll be solved this year, so please consider implementing the clear, and then try to solve the bugs. If you insist on doing it in the other order, we'll basically be left where we are now, having to clear it by hand or with a batch file.

NinjaTrader_LuisH Thank you for your commendable effort to streamline visibility. Where then can we see the pending feature requests?

Is there the features requests list/database page with numbers of votes and button for users to add/remove their votes along with the form?
Is the ballot removed and users can see/check which feature gets next implemented?
Is the select features plebicite done monthly, with monthly ETA delivery date, evey month?

Hello QuantKey_Bruce and PaulMohn ,


Thank you for following up on this item.

At this time this is a way for us to centralize all new inbound requests, rest assured the requests that were submitted prior to this form's existence are still being considered for implementation by our development team.

Since the nature of the OP's request was brand new, this form became relevant.


At this time, there is no public database for us to share with you.



Thank you.

No features requests / votes visibility to user whatsoever going forward?

[QuantKey_Bruce]

Surely you can see that this is a downgrade for users and not an upgrade. When the suggestions are on the forum users can interact and brainstorm about a better future for the benefit of all including NinjaTrader. Funneling all suggestions onto a form where they disappear from user visibility means an end to this interaction and synergy. Why is there a forum then at all if every post basically leads to a request to put something into a form where the thread goes to die?

[PaulMohn]

NinjaTrader_Brett any lead on users serving database disclosure for the new features requests policy?

... When the suggestions are on the forum users can interact and brainstorm about a better future for the benefit of all including NinjaTrader. ...

I can see your concerns ..

Why not try both ... Support the NT team internal process improvement and also start a thread about the feature request here in the forums. As long as you include something like a very distinctive title or visible request create number in your forum post the NT team would be able to tie the two together.

Hedge.

Well, among other things, there is no create number or any other feedback of any kind made available when you submit the form. There's zero visibility after that point, so it's basically going into a black hole never to be seen or heard from again, nor is there any way to reference it except by quoting it e.g. saying the exact subject and date and time - but that's what we have here already on the forum yet with so much more functionality and ability to interact.
