2155 is the 400 ticks accumulated profit target for 101indicators's traders who had owned the 101indicators On Futures Trading book. The target 2155 was only traded on last Thursday (10/9/2015), one day late as compared to the indicator Y.
Both had a late achievement this year.
101indicators's traders, who have "forgotten" the main focus of the book, are advised to read more often as we always wish to say - read 100 times a book is better than read 100 books! Be a disciplined trader!
See the page 153 and 154, and practice it and you should get the 400 ticks that worth $10,000 a contract size basis. However, it is important to have good trading rhythm discipline too.
We will post a write-up at the end of this year or early next year to tell you where is the accumulated profit and loss for the year 2015.
Cheers!
