I have to disagree with most of you, 100's different ways of scalping and I consider myself a scalper. I will on aggregate for the day between automation and any manual trading I do exceed 300-500 scalps per day per 24 hour symbol, risk on all of them exceeds any profit I might be able to make(my thoughts are why take a loss if you don't have to do so). And I enjoy the most of being in the 40-80% of making that one tick as this is the most consistent, by averaging down, all exits are one tick of original entry, so other entries am getting out between 2-6 ticks profits, am constantly testing to expand this 40-80% range. And while trying to prove something else, by error discovered patterns within the "book" or "price ladder", If I let it run full out, would do thousands of trades of ES in a 24 hour day, but always refining so as not to be a hog and put a limit of one signal an hour on both. If didn't ave down, maybe 1-2 losses a year if that, but ave down does produce more profit, and when price action rules dictate, a lose for someone else would occur, on average that would nail one tick gain cause average price went down. I would never trade a system where I didn't have an 90% edge.
I can read price pretty well of one minute and larger timeframe, BUT all based on percentages, can change opinions much faster than I can post one minute frames, LOL, almost every single time I am trying to learn to be more patient to stay in longer, prices will hit area of what I would have targeted and end up getting nothing for my time as trying to stay in longer, LOL
Any time people who have said "not to" or "can't be done", I view most as challenges and accounts be rewarded when I accomplish. On average in scalping for day sessions will average $8-23 per trade after fees, more trades the average goes down. Most people concentrate on making most money whereas I spend my time in my cave trying to get losing percentages and drawdown down. I ave down on each signal, down 5 price levels. Shutdown for the day does occur at 3 full losses, but due to reverses that cause some loss do not count, many trades are reverses as I try to go from wave to wave and get pieces of it. Most signals are counter-trend when entered.
I don't take one tick profits cause they are there, targets are based on ranges of one minute timeframes or 30 second timeframes, so original target be 4-8 ticks. Often times weak longs are my targets to reverse as they have losses or break evens. And most people will not say, if not for scalpers, they have larger spreads and get much slippage.
