Came across this archive in the thinkScript Lounge:

12:48 Mobius: I was recently asked to work up a scalping system for index futures trading. I agreed to do so as long as it could be shared. The criteria was

1) 1 to 3 point trades avg.
2) clear signals
3) 60% or better win rate

The trading method would be based on 2 contract entries. Risk defined by user but typically 2 to make 2. Risk Off defined by user but typically 2 points for one off and one runner. Sell signal for trade off at latest. I've been testing this for about a month. It works well with /ES. I've not tested it with anything else. Here is the study:

Code:
# Scalper
# Mobius
# V01.01
# Notes: Area between red and green horizontal plot lines (gray continuous cloud plot) represents body of trend. Area above and below red and green horizontal  plot lines represents tail accumulation and distribution. Price will be more volitile in tails. Trading at signals is good for quick scalping trades.

# End Code Scalper

A couple of notes from Mobius, the developer of this script:

12:49 Mobius: As always I suggest living with any study for a while until you understand it before trading it.

12:51 Mobius: The signals will not repaint. And they are not early or late. So you need to be comfortable pulling the trigger when you see the signal. It's scalping and thinking too much.

12:55 Mobius: I've been able to easily clear 6 to 10 points a day with that study over the testing period. With few bad trades more than a couple points

12:56 Mobius: Seems best trades are out of the gate at RTH open

12:57 Mobius: spoke.. I'll use 2min, 5min and 15min depending on how volatile the market is

13:00 Mobius: Good clue on how volatile the market is, is ORB. if the range is 10 points or less the market is probably melting up and 15min is easier. If 20 points or so 5min. Large Opening Ranges of 40 or 50 points and 2min and it's wise to lighten up in risk. I'll often trade down to 2 contracts if the market is super volatile. Even add to positions of we're getting 10point bars

Question - Do you short below the arrow or below the RED Line and same for GREEN ARROW AND GREEN LINE. . As I notice the arrow appears once it's already down. So I would like know you're thoughts ..Thank You for this great community.

@sbwcws I'm not too sure honestly. I hope there would be more to the indicator. But I was only able to locate a couple comments from Mobius which I already included above.

# Notes: Area between red and green horizontal plot lines (gray continuous cloud plot) represents body of trend. Area above and below red and green horizontal plot lines represents tail accumulation and distribution. Price will be more volitile in tails. Trading at signals is good for quick scalping trades.

So do you just go long and short at every arrow?

Hi BenTen!

I have been testing this indicator out with moderate success. Thanks for sharing!

I am trying to add an alert for this every time an up arrow or down arrow prints. This is what I've tried so far with no success:

Can you let me know what I am doing wrong? I'm a newbie at coding/thinkscript and I can't figure out what's wrong. Thanks!

@donger This should work:

I wonder what the difference is between upSignal and up2Signal, and dnSignal and dn2Signal.

"Area between red and green horizontal plot lines (gray continuous cloud plot) represents body of trend. Area above and below red and green horizontal plot lines represents tail accumulation and distribution."
upSignal and dnSignal are when price crosses green line
up2Signal and dn2Signal are when price crosses redline

@MerryDay Sounds good. Is price crossing to the red or green areas the entry signals. That’s what I am gathering looking at historical values.

@donger Which arrows do you go long and short?

The arrows are signals for this indicator. There are also different cloud colors that provides additional information depending on your strategy.
I only use the arrows as confirming signals for my various strategies so I cannot say whether they are good for entry in of themselves. I personally never enter my hard-earned cash into a trade based on any one signal alone.

Same here. Since I am new to this indicator, I don't fully understand all the arrows and regions. For example, if it is in accumulation phase, and you get white up arrow or green up arrow, what does it actually mean? How to you trade that scenario? Also, as you mentioned, there are 3 regions, green, red and gray, and arrows happening in these regions.

Mobius says he has been successful trading the signals, but doesn't say which signals in what regions.

@barbaros Again it depends on your strategy, as well as current market conditions and which assets you are trading; all of which are just some of the variables that drastically affect how I trade. There really is no Holy Grail.

@MerryDay I agree with you about "no holly grail" for indicators. However, that was not my question. There has to be a rule book for this indicator. I don't think "depending on market conditions" quantifies it well.

I think I understand this better after watching it live. I took a very cautious trade this morning at 10:25am for /ES. I exited at +1 point gain but it could have ran to +4 if i let it. You definitely need to pair it with other indicators to confirm though.

Having a hard time figuring out stoploss levels. I didn't trade this. It would have been profitable shorting eventually, but would definitely stopped with a tight stoploss.

Looking for a trend/reversal on a higher agg chart is a common start of most strategies. I have a half-dozen strategies to spot trends and reversals but only saw one strong setup on the /ES today. There was a Stoch cross along w/ a PSAR cross at 10:45 today on the 15min chart. But nothing subsequently formed on the tick chart.
So I traded equities today. And surprising for the market conditions, many of my trades were long.
Here is one example. QDEL setup a strong bull trend on the 15min chart which was also reflected on the one minute chart:

The trend started at the Mobius scalper green line. I could have entered the trade when it crossed the red line but going long against market conditions is not my trading style. But as you can see all my indicators were pegged, so I decided the ride up the 2nd half of the scalping line…
I usually exit when the SMI crosses below the SMIavg and or the Derivative RSI Oscillator starts to drop; both of which happened in this trade.
My conditional sell order is set for when the scalper's helper's red candle appears but I usually leave the trade earlier than that.

My six losses aren’t a reflection of the scalping indicator or a reflection of my trading. There is no Holy Grail. Even the best setup goes south sometimes.

@MerryDay Thanks for your response. I trade on indicators, patterns and support/resistance to take out emotion as much as I can. I am just test driving this indicator to see if it fits well with my other indicators. If this indicator is meant for trend confirmation and not entry point identification, then it won't be able to replace my primary indicator to pinpoint entries. I thought the initial post was about mobius' experience of scalp entries using this indicator.

Later in the day, /ES rallied. My midterm indicators showed the trend reversal, but the long term indicators stayed bearish. The long trade had a more clear entry point with this scalper indicator and a less volatile trend following it. Although I traded the long reversal, it was going against my long term indicators. It worked out to 12 point reversal to 200SMA for \$700 gain on 2 contracts (minus commissions, thanks TDA). I'm glad I had a runner to capture it.

It seems like you time your entries differently and we may have a different trading styles. And again, I understand that there is no Holly Grail of indicators. I'm just trying to understand the intent of this indicator and if I can adapt it to my style of trading. It has a lot of potential though.

The Indicator works exactly as Mobius said:
with clear signals and 60% or better win rate

As I mentioned only one setup was signaled at mid-morning today and the ROI wasn't worth it.

@MerryDay he also says to scalp at 1 to 3 points. I can’t see it clearly on your chart there. How many points do you allow it to run?
