Here are the steps to downgrade your Platinum / Gold membership to Silver:
1. Go to your Dashboard and click on Update my subscription.
2. On the Selection page choose two bots Weekly making sure that the % distribution is 100% and click on Next.
3. You will arrive in the validation page where you must set the amount of your allocation to 1000€ (basic parameter for the Silver plan):
4. Click on Save.
Warning: If you currently have Hourly or Daily bots activated, this will close their positions.
Also if choosing two bots forces you to deactivate one or more bots, obviously their positions will be closed.
In case these positions are in the negative, it may be a good idea to postpone your subscription change.
