EDCT VS EDDiscovery

I agree with /u/SkynetGDN but if you are in a hurry the bare minimum is 5.3B for the carrier, refuel, repair, and armory, one week of maintenance and 100M working cash. As soon as you get the carrier you'll need to find a port with large pads selling at least 25Kt Agronomic Treatment for under 3K/t. Jump your carrier there and fill it to capacity. Now find another dock buying at least 30Kt for at least 13K/t, and unload your carrier. You have now made 250M, which is enough to keep the carrier lights on for a few months (your maintenance with RRR is about 10M/week). Also consider getting elite dangerous carrier trader which will help find other potentially profitable routes. WARNING - EDCT is currently broken. don't use it until the 3.0 update comes out.

Unhappily it seems there is only EDCT but this is currently not working and all other trade route planners etc are for normal ships. I understand why it needs a lot compute power so there are no websites. Then I started clicking random commodities in inara/eddb and comparinng all the numbers. I had in mind that some more recent guides suggested Agronomic Treatment but things like Gold, Platinum or Bauxite seemed way more profitable.

For commodity and location, there is a specific tool for it, Elite: Dangerous Carrier Trader, which is also linked in the sidebar.

The information for this trade was gathered by EDCT. You can download the tool here: https://github.com/Fi0x/EDCT/releases/latest.

Right - the tritium cost depends on how far you jump and how full your carrier is. You can use the Fleet Carrier Router to get a close estimate. Normally the first jump is cheaper since you will be empty or nearly empty of cargo. Here's my post on bulk trading. You may also want to get a copy of u/Fi_0x's Carrier Trader Utility

EDDiscovery

That's one of the things I like about EDDiscovery's text-to-speech plugin, when you're jumping to a system where you'll arrive at a white dwarf / neutron star it gives you an audible warning to throttle down during your hyperspace jump. Something along the lines of "Warning: star is dangerous. Throttle down now!"

EDDiscovery or EDMC to update the EDDN and have useful information at your fingertips. I prefer EDDiscovery, hugely useful for explorers. Link your account to keep your info up to date and keep the community up to date to allow nearly all these other tools to work.

YouTube, Reddit, and the forums are your friend, there are also many the third party sites and applications available to help you to navigate and locate facilities within the game. The most commonly recommended site is Inara and the applications recommended to support it are ED Market Connector or ED Discovery. The applications send market data that Inara use to keep track of the trade markets, they include search functions which help you to find what stations have what services, including what ships and modules are available. Inara can also track your commander data to if you make an account and link it to your Frontier account.

(In case you haven't done so yet I suggest running EDDiscovery or EDDLite so it'll be recorded/updated to EDAstro.)

On PC I was using EDD, which integrates with sites like Inara.cz

My personal choice at the moment is EDMC; it has plugin support with some being very useful for exploration. Already mentioned is EDDiscovery - this is a more 'full on' tool but it's packed with features. There's also a new-ish one I've not yet tried myself that's designed to be far more light-weight; EDDLite.

Oh also a great utility to have installed if on PC is EDDiscovery it provides a ton of information that can be very useful. If you ever setup accounts on 3rd party sites such as EDSM, Inara, Coriolis, ED Shipyard, ED Astro, or EDDN Network among others it can integrate with those accounts as well!

If you run ED Market Connector or ED Discovery in the background, they send the market data that Inara uses to track commodity prices.

EDDiscovery, Organic scans window/tab. It will also tell you the total value before the bonus.
