Here is a study that I created. It's all original. I think it helps give some perspective to what the price is doing. If someone wants to translate it into another language, please feel free to do so. If anyone has any suggestions, or wants some modifications, let me know. If anyone wants to modify the study, feel free to do so.

If anyone has observations or suggestions about how to trade this study, feel free to post a follow up.

The basis of this study is very simple, it's the highest high or lowest low of the last 10 bars, BUT starting from 3 bars back. It's very simple. That is the foundation of the study. Everything else is just accessories. The code comments explain the signals shown on the chart and what they mean, and how they were derived.

A core principle of how I trade is to take profit whenever a good opportunity presents itself. Personally, I find this practice suits me, and works well for me. It often means that I miss out on some profit, but it also means that I'm constantly locking in profit, and often am able to get back in at a fairly good, if not better price.

I think this study has aspects of that perspective. I call it a price channel, because that is how it looks. The study also keeps track of recent PRIOR highs and lows. So it shows not only the current high and low, but the prior high and low. This differentiates it from something like Bollinger bands.

Code:
#Created by tradescripter
#Last Update May 20, 2011
#Green arrows pointing down are price highs.
#Red arrows pointing up are price lows
#Price highs and lows are determined by a few different methods.
#One method is to assume a price high or low if the length of the bar is greater than the average
#bar length, plus one standard deviation.  In other words, if there is an unusually big price
#move on one bar, a price high or low is assumed.
#A price high and a price low may not be a trend peak or bottom.
#Many of the price high and low signals are one bar early.  Take that into account.
#As soon as you get an signal, you must decide whether it's trend peak/bottom or not
#If you think it's not the end of a trend place an exit order to take profit just over the current high
#or under the current low.  If you don't get a fill almost immediately on the next bar, you must
#adjust your exit to a smaller profit within seconds, or use a market order to take profit.
#If the price high or low is a trend peak or bottom, the price probably won't go higher for a peak
#or lower for the bottom.  So you must decide on a strategy for taking profits.
#Whether you take profit immediately on a signal, or wait for the next bar, either way you will loose out on some
#profit.  You must decide when it's better to take profit, at the signal, or just after the signal.

#There is often a price high when the price first hits a prior high after being under the high
#for a while.  That potential price high is shown by a magenta arrow down over the high of the bar.
#A potential price low, bowncing off support of a prior low, is a blue arrow.

#Stop losses are shown by squares.  The stop losses turn out to also be points of price highs
#and lows.  A long stop loss is show by a red square.  The long stop loss is often a price low however.
#You must use your discretion on how to trade it.
#A price high signal, and a stop loss signal often occur on the same bar.  That may be a double
#confirmation that the price is at a high.  You must use your discretion.

#Prior highs and low are also shown  The prior highs and lows are the "Stepped" horizontal lines.
#So you can keep track of recent prior highs and lows.

#I have not back-tested this study.  I have no idea if it is any good or not.

Cool Re: Support and Resistance Channels - ThinkScript

This is a great script. It looks profitable in several different time frames. As you may know, Ondemand is not working properly but i can't wait to test it. Good works

Thumbs up Re: Support and Resistance Channels - ThinkScript

I used your study today. Let me say that your a genius. Long story short. After studying the indicator and finding the best time frame to trade it, I made up all of this weeks losses in 1 day and can't wait until tomorrow. Thanx again and great job. BTW do you have any other's to share? Don't get lost if i make it big, I will drop you a token of my appreciation. Count on it.

Funny. I was up all week and I lost it all back today. I must have been trading the opposite of you. Wish I had those channels.

Re: Support and Resistance Channels - ThinkScript

I can't get it to verify. Can you upload a ELD. Can you upload a picture of the indicator plotted.?
