"Market Delta" Footprint for TradeStation

Market Delta is 3rd party software that provides interesting ways of viewing bid/ask information. This information could be useful for analyzing market behavior as price approaches a key support/resistance level.

For those that use TradeStation, I have created a simulation of Market Delta. Note that TradeStation provides a snapshot of the bid/ask so it won't be accurate most of the time. Therefore, I have provided an option in this analysis technique to use upticks and...

Re: "Market Delta" Footprint for TradeStation

Is there any way to convert this ELD into EFS to use in esignal?

Re: "Market Delta" Footprint for TradeStation

Double-check to see that this line is not written twice:

"errLine 23, errColumn 2, errLineEnd 23, errColumnEnd 2"

And the end of each line should have a semicolon ";".

Re: "Market Delta" Footprint for TradeStation

Hi, ant:
very much interested in your code. I used to be a programmer and dba on unix platform for a few years and is trading full time now. I want to code some programs, such as the one you posted. How do I get started? any book you recommend for me to read? I have not coded anything web-based.

thanks

Hi David,

I'm assuming you are refering to developing TradeStation indicators... As a programmer, I think you'll be able to pick up EasyLanguage fairly easily so I would suggest taking TradeStation indicators that already exist and review how they are written. Learn how to use arrays, draw trendlines, print text, create functions, read and write to a file, how to process data on every tick, etc. Take a look at the online TradeStation User Guide. There are a lot of TS indicators around so just take one that you think would add value to your trading and modify it for the learning experience. I would also learn about the TradeStation API (EasyLanguage Extension Software Development Kit - a reference guide) so that you can write DLLs for TS. It's pretty straightforward I think. Other stuff you can learn are how to use global variables and the ADE. Global Variables allow you to pass data between windows in TS. Do a search at the TS Forum for more information. This is how I started out with EasyLanguage. Hope this helps.

Re: "Market Delta" Footprint for TradeStation

If you're going full algo trading however, that is, not wanting to sit in front of a rack of monitors all day long, then TS may not be your best bet. Or if you want to trade the futures TS is limiting. There are systems out there which will allow you to code up strats that will do pairs and composites trading, venue blending trading, etc. But if you're just looking to trade using your brain as a probability engine then TS or eSignal work well enough.

Re: "Market Delta" Footprint for TradeStation

Here is a modification of Ant's MarketDelta 'footprint' code that implements a threshold free, dynamic coloring gradient for the balance at each price.
The coloring algorithm serves as a pretty good template for auto-coloring of other indicators, etc. See comments in code.

Re: "Market Delta" Footprint for TradeStation

Nice to see someone doing maintenance and updates on Ants code. I have some footprint code that does auto shading but it seems to look 'kind of pale'. I'll give this a spin sometime

Thanks to both,

Thanks for doing this, is there anything special I need to do on the chart?
I installed it but don't see anything on a 15 minute chart, is there something I'm messing up on?

Thanks

I haven't tested it yet, but it should only work in real time. (No Historical data).
