1. ## Amibroker - Scanning for Trading Ideas

Dan was looking for ideas for scans a while back. I found an old Pull Back Scan that i got somewhere...

I then combined it visually with an ADX and Simple Momentum Indicators and presto, you have a nice little scan.

What i do is scan first, then transfer a portion to a watch-list.

Then eyeball them, but using the ADX and the momentum indicator. Then i look for patterns in stocks with strong trends.

Hope this helps anyone looking for a simple way to scan. Those with coding skills might want to scan for the whole thing at one time. I actually like eyeballing charts, its quite exciting to look through lots of charts with the view of finding opportunities.

IT might be nice for others to post some scanning ideas here...

Looks interesting mate! Thanks for that!!
I'll have to try move similar criteria into a free screener until I the full version of AB and PD

Thanks again

3. ## Re: Amibroker - Scanning for Trading Ideas

A couple of people are still wondering how to look for trading ideas. Here is how i do it.

1.) Sign into The Chartist and check the Power Setups. These are the ones i normally always take, then i scan for my own as well, only taking ones that are really good patterns in strong trends. Quite often I'll find a few of the same same stocks as The Chartist.

2.) Open Amibroker
a.) Run my Pull back Scan on the Russel 3000
b.) Isolate the sell signals and move them to my watch list "US Stocks - Shorts
c.) Got to watch list and load my Grail charts template.
d.) Look, i.e. Eyeball, for bearish continuation patterns, flags, pennants, ledges. Once the euities are in the list, you just down arrow through them, stopping to examine the more obvious patterns. If its not obvious, its not there.
e.) Keep the good patterns and move out the remainder.
f.) Repeat with the longs.

I just found this one, i like these well defined trend lines...lots of people watching it...usually a good chance to get some nice liquidation.

5. ## Re: Amibroker - Scanning for Trading Ideas

I had a thought of scanning for a daily ROC that is higher than any previous given day.

This is the line I took but it doesn't do the job. First I think the ROC for a particular day has to be known and then the present day ROC compared to any of those past days. In this case any of the past 21 days. Any fix appreciated muchly.

Code:
```// Percent change higher than any previous day

Day1 = Ref(ROC(C,1),-1); // Percentage Rate Of Change 1 day ago
Day2 = Ref(ROC(C,1),-2); // Percentage Rate Of Change 2 days ago
Day3 = Ref(ROC(C,1),-3);
Day4 = Ref(ROC(C,1),-4);
Day5 = Ref(ROC(C,1),-5);
Day6 = Ref(ROC(C,1),-6);
Day7 = Ref(ROC(C,1),-7);
Day8 = Ref(ROC(C,1),-8);
Day9 = Ref(ROC(C,1),-9);
Day10 = Ref(ROC(C,1),-10);
Day11 = Ref(ROC(C,1),-11);
Day12 = Ref(ROC(C,1),-12);
Day13 = Ref(ROC(C,1),-13);
Day14 = Ref(ROC(C,1),-14);
Day15 = Ref(ROC(C,1),-15);
Day16 = Ref(ROC(C,1),-16);
Day17 = Ref(ROC(C,1),-17);
Day18 = Ref(ROC(C,1),-18);
Day19 = Ref(ROC(C,1),-19);
Day20 = Ref(ROC(C,1),-20);
Day21 = Ref(ROC(C,1),-21);

Filter = ROC(C,1) > Highest(Day1 OR Day2 OR Day3 OR Day4 OR Day5 OR Day6 OR Day7 OR Day8 OR Day9 OR Day10 OR Day11 OR Day12
OR Day13 OR Day14 OR Day15 OR Day16 OR Day17 OR Day18 OR Day19 OR Day20 OR Day21);

AddColumn(C, "% Higher", 1.3, colorBlue, colorSeaGreen);```

6. ## Re: Amibroker - Scanning for Trading Ideas

Code:
```x = ROC(C,1);
Filter = x > Ref(HHV(x,21),-1);
Filter == 1;```

7. ## Re: Amibroker - Scanning for Trading Ideas

Nice and simple. Thank you rest n recuperation.

8. ## Re: Amibroker - Scanning for Trading Ideas

Code:
```// Percent change higher than any previous day

ROCcheck = ROC(C, 1);
Filter = ROCcheck > Ref(HHV(ROCcheck, Param("ROC Lookback", 21, 1, 250, 1)),-1);
AddColumn(C, "ROC Higher", 1.3, colorBlue, colorSeaGreen);```

Perhaps relevant to the current season....the alternative would be along the lines of risk-n-reward.

You could also scan for an increase in momentum!

Code:
```MomPrd = 1;
MomChange = 12;
Filter = ROC(C,MomPrd)>MomChange;
Filter;```
