One more contract: $30, or $21 with START30, charged once. It raises your position ceiling by one mini, or ten micros, for the life of the account. On an order of several accounts it is charged once per account.
It does not change your drawdown allowance or your payout caps. The same move in bigger size reaches your drawdown level in fewer ticks.
Stats, rules, payouts, exports, security and support come with every account. Nothing you can buy changes your drawdown, your payout split or your payout caps, and nothing is required to get paid. BiziSelect has no add-ons.
This article is a summary. Your signed Plan and Rules Snapshot, the Trader Agreement and the Payout Policy govern where they differ.
