You do not need to wait for selling transactions after you have made your purchase transactions, and you can sell at any time after the purchase transaction. However, you should be careful not to get stuck in the daily buy/sell limit while performing these transactions. You can make a maximum of 3 buy/sell transactions in 5 days with your Papara Investment Account. If you try to trade daily for the 4th time, you will not be able to make any buy/sell transactions for 90 days after the transaction. We set this limit based on United States regulations to avoid being banned from the stock market. If you have $25,000 or more in your Trading Account, you will not be subject to the daily buy/sell limit.
