With the little knowledge I have, I have seen a lot of people scalping and making it than those that does a full trading(hours, days) but they tend to lose so easily can we say it greediness or it's not advisable generally
To me scalping is just a pattern of trading just as any other pattern, and all of them have their own advantage and disadvantages, but to me what I think that is important is knowing the craft and how to react to what the market is giving you, not what you feels like will play out.
And while scalping it's very important that your decision making will be very swift and spot on so as not to miss any opportunity that comes begging, so what am trying to say is that no matter the system we are using to trade, all of them are ok, as long as we actually knows what is required of us, for we to succeed in the market.
