Currently, the trial period is fixed at 1 week. It would be useful if channel admins could choose the trial duration themselves, for example:
1 week
2 weeks
1 month
For signal bots, one week can be quite short to properly evaluate the service. Depending on market conditions and the trading strategy, there may only be a limited number of signals during that period, which makes it difficult for users to judge the quality, consistency, and behavior of the bot.
Allowing admins to offer a longer trial, such as 2 weeks or 1 month, would give potential subscribers enough time to see the strategy operate under different market conditions and make a more informed decision before subscribing.
