THANKS FOR THE PROMPT REPLY . REGARDING FORM DATABASES FOR SALE CAN YOU MENTION WHO HAS THEM , THE PRICE AND SUITABILITY FOR TESTING A SYSTEM . I HAVE NOT DEVELOPED A SET OF RULES, I JUST HAVE ON KEY ASPECT TO BUILD A SYSTEM AROUND . I WOULD PREFER TO TEST IT MYSELF AS I DO NOT LIKE PEOPLE TO SPEND THEIR TIME ON MY BEHALF AND ALSO BECAUSE I BELIEVE THE VALUE LIES IN PEOPLE RULING OUT HORSES WITH THIS FORM PATTERN . EVEN HORSES THAT ARE THE FAVOURITE IN PRE-POST MARKETS ALLWAYS SEEM TO END UP AT GOOD ODDS.
