Tutorial - Posting Trades:
If you post a completed trade and designate it as Closed, it'll have you enter both the entry and exit price. If you have separate comments for your entry and exit, when the trade is posted, the comments will be displayed in a single text block no matter what your formatting is in the text box.
If you post a trade and first designate it as Open, it will only have you enter the entry price of the position and comments can be added to the text box. Once the open position is posted, click the caret (^) symbol to close the trade. When prompted, enter the closing price and your closing comments. In this case, because the trade was posted in two parts, the comments will appears in separate block for the final post.
