Usage

let exchange = new Exchange(client, dashboard);

async function update(): Promise<void> {
  // Tick to update created orders.
  await exchange.tick();

  // Calculate new orders to be placed.
  let descriptors = ...;

  // Update orders by new descriptors.
  await exchange.update(descriptors);
}

Order update procedure

Active (assumed) orders are stored locally.

• Sort order descriptors based on their priority

• Cancel order with the same label and update calculated money/stock.
• Check money/stock:
  • If the the remaining money/stock is sufficient for the updated order, create the new order.
  • Else if there are active orders with lower priority, cancel the order with closest lower priority and do this step again.
  • Else throw an error or print a warning message.
