The news on the first Simulated Market trading day indicate that there will be a high demand for the Herta Puppet Plushie, Auspicious XV, and Owlbert Plushie.
Topaz doesn't include the Auspicious XV in her trade suggestions, but it would still be good to allocate some of your funds to purchase it in line with the news trends.

Based on the news in the second Simulated Market trading day, there will be a high demand for the Aetherium Wars Game Cartridge. Meanwhile, the demand for the Herta Puppet Plushie and Auspicious XV will likely drop, causing lower selling prices.
You should invest most of your funds into the Aetherium Wars Cartridge, then allocate some towards other items with Medium to High price fluctuations. Although these items may not have a high demand, you can still earn and cover more bases.

The news on the third Simulated Market trading day suggest that there will be a high demand for the Engine of Creation Part and Luxury 1-Day Tour. On the other hand, it's likely that the demand and selling price for the Owlbert Plushie will drop.
Topaz doesn't include the Engine of Creation Part in her trade suggestions likely due to the fact that it has a Low price fluctuation. You can still opt to invest in it if you want to play it safe, but it may be better to invest more into the Luxury 1-Day Tour and other profitable items.

The news on the third Simulated Market trading day suggest that there will be a low demand on Cycranes and the Astral Express Luxury Ticket. There will also be a high demand on the Rose Bouquet due to the rumours of some having the ability to think independently.
Topaz doesn't include the Rose Bouquet in her trade suggestions likely due to the fact that it has a Low price fluctuation. You can still opt to invest in it if you want to play it safe, but it may be better to invest more into other profitable items.

For the last trading day of Simulated Market, there will be a high demand for the items mentioned in the news listed above. However, Topaz suggests investing in more items with High price fluctuations.
To guarantee earning a profit, you can go all in on the Aetherium Wars Game Cartridge! Since it's a trending item with a Medium price fluctuation, it's the safest and most profitable item to invest in.

View news updates to see what items are trending for the trading day. Popular items highlighted in pink will likely sell well!

On each item are different colored lines. Green means low price fluctuations, orange means medium price fluctuations, and red means high price fluctuations. You must compare the news and the price fluctuations if you wish to adjust prices without Topaz's help!

Once you've gotten an idea of what items will sell well, select how much of each you want to trade. You are not required to use up all your funds, but they won't carry over to the next day so it's best to use them all up!

If you're not sure yet about what to trade, you can click on Topaz Trades! to get her input and automatically select the items for you. You can either follow her suggestions entirely or tweak them based on your preference.

Luckily, rewards from the event don't require you to win all the Trading Competitions. Simply continue trading for the rest of the 5 Trading Days so you can get all possible rewards!
