Frequently asked questions.

Installation & getting started
How do I install a NinjaTrader 8 indicator?

Every indicator ships as a single .zip — NT8 imports it in one click, no manual file copying.

  1. Open NinjaTrader 8.
  2. Control Center → Tools → Import → NinjaScript Add-On…
  3. Select the .zip you downloaded. NT8 imports and compiles automatically (green confirmation).
  4. Restart NinjaTrader (recommended after the first import).
  5. Open a chart, right-click → Indicators…, find the name, AddOK.

Full walkthrough with screenshots on the installation guide.

Where do I download my indicator after purchase?

Right after checkout you land on a confirmation page and receive a receipt email from Creem, our payment provider, with your download link.

Can't find it, or the link won't work? Email us your order number and we'll send you a fresh copy directly.

I didn't get the download email — what now?
  1. Check spam / junk / promotions — a first email from a new sender often lands there.
  2. Wait 5–10 minutes for the order to confirm.
  3. Search your inbox for "usefulindicators" or the product name.

Still missing? Email [email protected] with your order number and checkout email — we'll resend.

The indicator won't compile — what's wrong?

Almost always one of two things:

  1. An older copy is conflicting — Tools → Remove NinjaScript Assembly, remove it, re-import.
  2. NT8 needs a full restart (tray icon → Exit, reopen).

If neither works, email us the exact error (screenshot of New → NinjaScript Output), your NT8 version, and the product — we usually have a fix within hours.

Can I run it on multiple computers?

Yes — your licence covers personal use across all your own machines (desktop + laptop, home + office, main + backup). No machine lock, no activation server, no key to enter. Just import the zip on each.

What's not allowed: sharing with other traders, posting the file, or reselling.

Compatibility
Will it work with my data feed (Rithmic, Kinetick, IQ Feed)?

Yes — every indicator is data-provider agnostic. They read NinjaTrader's bar data, not the feed directly, so any provider NT8 supports works: Rithmic, Kinetick, IQ Feed, CQG, Interactive Brokers, and more. If a less common feed behaves oddly, email us — we'd want to know.

Does it work outside US timezones?

Yes — built and tested for international traders (about a third of users are outside the US). Time-based indicators include a Timezone setting (System Default / UTC / Eastern / Custom). On the default NT8 setup, everything just works; if you customised your chart timezone, set the indicator to "Custom" and match it.

Will it work with prop firm accounts (Topstep, Apex, etc.)?

Yes — to an indicator, a prop account is identical to a personal one (same NT8, same data, same engine). Confirmed across Topstep, Apex, Earn2Trade, Take Profit Trader, My Funded Futures, and others. The indicator just draws on your chart — it doesn't touch order flow. Do check your firm's rules on third-party tools during evaluation.

Does it work on tick, volume, range and minute charts?

Most work on every NT8 chart type: tick, volume, range, second, minute, hour, daily. Time-based tools (session VWAPs, IB ranges, news) are designed around time bars; volume tools need a market with volume data (futures/stocks have it, spot FX often doesn't). Each product page lists supported chart types.

What NinjaTrader 8 version do I need?

NT8 build 8.1.x or later — that covers virtually every active install. Check yours under Help → About; update free via Help → Check for updates. We don't support NinjaTrader 7 (end-of-life).

Orders, licensing & account
Is this a one-time payment or a subscription?

One-time payment. No subscription, ever. Buy once, own that licence forever — no recurring charges, no expiring access. Free updates included for life. We're traders selling to traders; charging you again for software you already own isn't how we run this.

Is there a licence key to enter?

No key, no activation server, nothing to enter — after import, it just works. We avoid keys on purpose: they break, servers go down, and they add friction. It's honour-based: one licence per customer, used across your own machines.

Will I get a receipt or invoice?

Yes — Creem, our payment provider, emails a receipt for every order, with tax itemised where applicable. Need an invoice with specific billing details (company name, VAT number)? Email us with your order number and we'll sort it out.

Can I share my indicator with a friend?

No — the licence is personal use only (your own machines, not shared). Sharing the file, posting it, or bundling it elsewhere is a licence violation and results in revoked access without refund. If a friend wants it, please ask them to grab their own copy — that's what funds free updates and new tools.

Payments & refunds
What's your refund policy?

Laid out in full on the Refund Policy. To request one, email [email protected] with subject "Refund — [product]" and your order number. If you have a moment to share why it didn't fit, we read every reply and use it to improve.

Is there a free trial or demo?

No time-limited trials — but our free tools are the honest demo: full products, no email required, no cut-down features. They show you exactly what our code quality looks like on a real chart before you spend anything.

What payment methods do you accept?

Payment is handled by Creem, our payment provider: all major credit and debit cards, plus additional payment methods depending on your region. Tax is calculated automatically at checkout based on your region.

Updates
Do I get free updates?

Yes — free updates forever. Bug fix, performance improvement, or new feature: you get an email with the updated zip, automatically. No re-purchase, no upgrade fee — applies to every version increment (v1.0 → v1.1, v1.x → v2.0, all of it).

How will I know when an update is available?

An email to your purchase address with the updated zip, a short plain-English changelog, and install notes if anything changed. We don't spam — emails only go out for real new versions. Add [email protected] to your contacts so they don't get filtered.

Will my settings be preserved after an update?

Yes — NT8 stores settings per chart instance, separately from the indicator code, so your configurations carry over. New features default to off / neutral values, so an update never changes how your chart looks unless you opt in. To be safe before a big update: File → Workspaces → Save.

What if a new NinjaTrader build breaks an indicator?

We test against new NT8 builds as they're released. If one breaks something, we ship a free patched version — usually within 1–2 weeks — and notify you by the normal update email. If NT8 updated and something's off before you've heard from us, email support; you might be the first to flag it and we'll prioritise.

No questions match that search. Try different keywords, or email us — we're happy to help.
