Enveloping requires constant work. Use "cance if close" orders (small joke)...we cancel when the bid/offer creeps to the price we have entered, and try to only get hit when there is a bigger drop or rise from the prior bid offer.
For example, on Tuesday I entered about 285 orders, and was only filled on about 80 or so. I would buy at, say xx.20, and then bid xx.10 and offer at xx.32. If the bid on the stock came down to xx.12, I would "update" the xx.10 to xx.05 or so. By keeping this up, and never adding more than a couple of times in the same direction, we can do well during those days (too many days sometimes) of "troughing" up and down in a certain range.
The same "rules" apply to individual stocks as always. We monitor relative strength, momentum, sector, etc. If you're doing this manually, it is a bit intense to do it on more than 1 or 2 stocks at a time. If you automate, you can monitor more stocks easily. I suggest that you get a high success rate manually before attempting automation.
Hope this helps!
