Quote from quin8670:
I agree that trading one lot can allow you to develop a high level of precision. But I think the precision on your entries is what counts, which you can achieve with more than 1 lot. The advantages of scaling out of positions are a key edge for me. Lock in a bit of profit early in the trade and then let the rest ride in hopes for big moves that allow you to get exceptionally high R:R.
In situations like this, you could have just taken part of the position off (even 20-30%), which could have put you at ease and allowed the rest of the position to work.
As I said I have almost no experience scaling positions, so I'm not qualified to pass judgment on it. I have only my opinions about it. My mentor does not scale in or out and he's been trading for I don't know how many years. Another professional trader I met when I started day trading, who's now in my Skype group, trades multiple lots, all in/all out. We trade similarly, with precision and tight stops.
In my situation mentioned, I basically violated my rule, so whether or not I traded multiple lots is irrelevant. If I traded 2 lots and took one off at 10 ticks, I still violated my rule. I reduced my R:R, even if it was on part of a position.
I've had many conversations about this. We're always debating the value of trading multiple lots and taking off part for a scalp, letting the rest run (Al Brooks and Mark Douglas seem to be much in favor of this).
I would like to see the trade blotters of those who scale in/out, because it would help me understand the environment in which it's used and how the profitable traders handle it. xxxskier posted a few blotters in the past and it was enlightening to see that style of trading.
