These dynamic cards fluctuate hugely in price depending on the performance of the team and player - and , this year, presumably, based on their country's, too. This is evident in the price graphs found on FUT comparators, where stars strikers will increase in value prior to the game, and then go through the roof after scoring, or drop without a trace if the team is in the back.
The best way to make money from the cards is to usually buy them in neutral times keep them in your possession, and then to sell them after the excitement. For instance Liverpool's Darwin Nunez has had a slow start to his life at Merseyside with two goals from the league over his opening seven matches.
After an unsatisfactory 3-3 draw against Brighton and with tough games in the near future the OTW price - three days post-release - is at or between 70k and 70k coins. A savvy gambler could decide this 'low' moment to purchase one, then decide to sell it before the next Liverpool game starts off, especially when Nunez is on the lineup. An investor who is more cautious might decide to keep it until the game in the hope he scores, but the risk is higher.
One thing you should look for when using OTW cards is when upgrades are already "priced in'. Everyone knows Man City are going to have to win 3/8 games for Haaland the first OTW upgrade, for example and that's part of the reason behind the exorbitant price in-game. Don't fall for the trap of buying players who will certainly get those three wins in hopes that they'll increase in value when the time comes around. Most likely, it could lead to a large number of investors trying to make money at the same time, making the price go down.
Ultimately, Ones to Watch cards are predictable in some ways and unpredictable in others.
