Modified Schaff Trend Cycle Indicator for ThinkorSwim


My first post folks and I'd like to say hey and share two of my first modified indicators. I've taken quite an interest in making/modding indicators and would like to offer the community some tools they may find helpful for education or actual trades.

As for these first two that I would like to share, one is just the MACD with color and Bollinger Bands. The second is a modified Schaff Trend Cycle indicator, which MACD users may find useful. It has two lines and a StocRsi. Full Disclosure, I do not know if I am allowed to post modified indicators that come with THinkorSwim. Please remove if this is the case.

For those not familiar with the Schaff indicator, it's basically an amalgam of the MACD and RSI that can be looked at several different ways. I've found it to be an absolute tool for my trading and has not left my charts. I won't get into my trading thesis, but here are a couple of ways i've found my modified Schaff can be utilized...i'm sure there are others. A few are as follows:

1. An added tool to the MACD where you can find new entry points within a MACD trend.
2. Used alone, you can use two Schaff lines (which my modification has) as a way to set one line up for the trend and one for the pullbacks in that trend.
3. As a confirmation tool to support/resistance trading.
4. There is also a StochRSI line to help confirm what the Schaff wave line is indicating.
5. I use it as a confirmation to very basic Elliot wave trading. The wave line helps me a great deal to see the continuation of a trend, especially when the retrace is bouncing off a Fib 50% line.

You will find a "Trend" setting where you can use longer length periods to give you the trend. At the default settings, the trend line is like and very closely follows the 'Avg' line on the MACD. You will also find a "wave" line which you can set at faster settings to give you entry points that are moving in the direction of the trend line. For example, if the trend line is on top, you will find the wave line may fall to the oversold area showing a pullback. The default settings are 12/26/9. Yes, MACD settings and will closely follow the MACD Value line. The included StochRSI can help verify the wave movement.

I would like to point out that I modified the Schaff Trend indicator to help with my trading thesis, which I know well, so for me, it's just a tool. I'd be more than happy to answer question to those that may see some use to it.

Also, the MACD indicatior I'm sharing has clouds for the Bollinger Bands. I'm not very good with the code yet, and i'm not even sure if there is a way to set up an on/off cloud setting, but just add a '#' sign in front of the two cloud lines in the source code.

Well, thanks for looking, and looking forward to seeing some of your trading methods.

If I goof this posting, please advise as to how to correctly post code. Also, if you see that my very beginner code can be optimized, i welcome suggestions.
