Welcome to

Welcome, Guest!

This forum was established to help traders (especially futures traders) by openly sharing indicators, strategies, methods, trading journals and discussing the psychology of trading.

We are fundamentally different than most other trading forums:
  • We work extremely hard to keep things positive on our forums.
  • We do not tolerate rude behavior, trolling, or vendor advertising in posts.
  • We firmly believe in openness and encourage sharing. The holy grail is within you, it is not something tangible you can download.
  • We expect our members to participate and become a part of the community. Help yourself by helping others.

You'll need to register in order to view the content of the threads and start contributing to our community. It's free and simple, and we will never resell your private information.

Midas Explorer

I updated the post (2 back from this one) about Midas Explorer to clarify some points. I do like it but this is user feedback, not any kind of advertisement. I am genuinely impressed by that product.

I am programming an automated trading system with a couple of other people. using R and python languages. Its time to define support and resistance and I am having hard time thinking of something satisfying, I came up with a couple of unconvinsing definitions. Any one can direct me to the straigh path?

I am doing the same thing, what I did is.

1) Any given quote must be defined with a PointType. These are High, Low, Both or None.
1.a) A High point is a point for which the previous and post quotes are lower, Low is the opposite, both means both criteria fit (it happens).

2) Later I define a support or resistance line as a quote with a value, starting date, and a tolerance percentage. This means That the next quotes do not necessarily need to "touch" the exact value.

2.a) Every High or Low point is a potencial support or resistance line.
2.b) I define an algorithm to test if if each subsequent quote either, touches, is on the correct side, or is on the wrong side of the line. If it is on the wrong side of the line then the support, or resistance is broken.
2.c) With a "Touch" the line is confirmed.
3.a) One break is allowed and this transforms the line in the opposite (support to resistance and the other way around)
3.b) After the second brake means the line is invalid and I define that date as the ending date for that line.

how many lines will you have depends on the size of your tolerance level, I found out that a value of +-20% works well.

Hope it helps!

Support & Resistance

I saw your posts on this subject and wondered what progress you have made in this area since these posts are from 2011 to 2014. I am looking to automate this process in either c#, Python or some other tradeable method.

Support and Resistance are the result of Market Makers pumping supply into the markets at specific price levels in an attempt to influence the markets.

do you think one main factor on these levels might be the $volume of options these market makers have sold at those levels and they need to defend them so that as many as possible of these options are going to expire worthless.
