G'day

I have recently taken an interest in horse racing after years of betting on sports with decent success.
I have been studying form guides for the last month, making hypothetical picks and just getting a basic understanding.

I'm hoping you guys could point me in the direction of where I can find info on jockey/trainers form, trends and some of the main things you look for when making your picks.

I have a good understanding of bankroll management and plan to bet within the limits my bankroll allows me. Line and margin bets are my bread and butter when betting on sports, I'm interested on which type of bets you guys generally place.

Apologies on all the questions in my first post here, but I haven't had much luck searching for the answers online and the punters I know don't look much further than recent form and barrier draw of a horse and are not much help.

Appreciate any advice, thanks in advance
