This may seem a bit unfair but it is not as if the online casinos are running a charity. They want to get you signed up, they want to get you coming back regularly and they do not want to be giving their money away for nothing to everyone. All of this means if you want to have the extra money that they enticed you in with, you are going to need to hang around and play a few more casino games. 

Just like the punter playing roulette in the casino as you never can get the odds in your favor. If you can’t get the odds on your side you won’t win. In day trading, all daily volatility is random and takes prices anywhere - so how can you key off support or resistance levels? You can’t, you may as well flip a coin.

A scalper is a person who holds a position for a very short period of time, attempting to make money off of the bid-ask spread. The scalper aims to make lots of very small profits with the idea that lots of small profits can add up. And it is a lot easier and quicker to make a 1 tick profit than it is to make a 10 tick profit. The best markets for scalping on Betfair are the UK horse racing markets just before the start of the race.

This is true whether the scalper is buying and selling stocks, oil futures or horse racing prices. And the key to success is speed: the faster you take your profits the less risk you are taking, and the scalper avoids risk at all costs.
