Getting set up takes about five minutes:
The page asks for an email address before it releases the file — type the email address your NinjaTrader account is under. Then press "Get the installer" and the download starts on its own. Your browser will probably hold the file and ask you to confirm the download — the installer isn't code-signed, so your browser can't vouch for who published it. Pick the option that keeps the file, usually "Keep" or "Keep anyway". The installer then lands in your Downloads folder.
Double-click the installer from your Downloads folder.
Open NinjaTrader 8 and import the zip file: Control Center → Tools → Import → NinjaScript Add-On → select the zip from your Downloads folder.
Restart NinjaTrader. Close it fully and reopen — the tools only load at startup. Then close it and start it once more. On that first start the toolbox puts its own skin, trading-hours templates and workspaces into place, and the second start is what makes NinjaTrader pick them up. Both starts matter, so don't stop at the first one.
Done — the tools now appear in your regular Indicators and Drawing Tools lists, under the CFT_Private_ToolBox names.
One more thing — your customer portal. Zoho sends you a separate invitation email to set your portal password (check your spam folder if you don't see it). You don't need it to download or run the tools. The portal is your account area — card, invoices, subscription:
