Quote from intradaybill:
The very act of scalping for retail traders is a catastrophic event. I used to be a scalper. It took a lot of energy and help from friends, market professional, to understand that it was more of an addiction than anything else to a retail trader and escape from it. I am not talking about market makers because those scalp by virtue of their job.
The first step to trading success is understanding that you have to minimize the impact of slippage and commissions and maximize profit. This can be done only with position/swing and trend trading. I know many won't agree.

u could scalp to earn slippage and spread from impatient traders ... , this is not our topic anyway , what could be the best protection for scalpers ?

Quote from intradaybill:
One protection scheme I used before was based on buying OTM options one month before expiration and you rollover 15 days abouts before expiration. This can protect you from a catastrophic event when you will go long for example and never see your price again....
It happened to me before when I was trading BP futures. I missed my limit to exit for one tick and the market plunged 300 ticks in a few seconds.
P.S. by the way, nowadays I trade mostly near the money options but I use the same systems for the underlines. I can tell you I have never experienced a more easier market to trade. Even if someone has basic TA knowledge this market is very easy. But, most people lost their money in 2008 and have no margin to put down now.
