Access means that the app allows you to use an offering under the applicable requirements. Activation is a separate choice about whether its decision engine is enabled. In between, there can also be a configuration step that selects the strategy for a mode. Understanding these stages helps you avoid two mistakes: assuming a subscription has started trading, and assuming that adding a card to a workspace has already turned its engine on. In the current strategy detail view, an eligible strategy that has not been configured for Paper can show Add to Paper. In our isolated demonstration, selecting that action adds it to the Paper setup with the decision engine off. This gives you a chance to review its settings. Read the returned label. Adding and enabling are separate steps here; do not assume that the first click authorizes new entries. Once the strategy is configured, the mode control can display Decision engine Off or Decision engine On. The Trading card and its settings also show enabled or disabled state. These labels concern that strategy in that mode. They do not establish the state of another strategy, another mode, or every exchange connection. Always keep the mode label in the same mental sentence as the engine state. Some offerings require a subscription or another form of access. Read the current price, billing interval, and terms before any real purchase. A checkout may take you through a separate payment flow. Starting that flow is not proof that it finished successfully. When you return, verify the access status actually shown. Our lesson uses existing example access and does not require you to buy a subscription. Access can also be affected by the offering's availability, an account restriction, or a version or lifecycle notice. If the control gives a reason instead of an available action, read that reason first. An access restriction and a connection problem call for different investigations. Clicking repeatedly or increasing a budget does not resolve every kind of unavailable state. Imagine that you have an active subscription but the Paper decision engine is off. There is no contradiction. You have access, but you have not currently authorized that engine to make new entry decisions in Paper. Now imagine that Paper is enabled while Live remains unavailable. Those labels can also be consistent because the two modes have separate requirements and states. For your checkpoint, describe the path as access, add or configure, review settings, then enable and verify. Do not compress it into subscribe and trade. In the next page, we will inspect the mode, account, and resource settings before changing the enabled state. That ordering gives you a chance to understand the limits before the strategy is allowed to use them.
