I want to develop a custom indicator that could plot aggregated normalized volume of 40 chosen stocks. The indicator needs to access 40 stocks' bid ask volume and price. I want to know whether esignal or tradestation support the following required features: 1. 30 days historical tick data; 2. Chart Indicator could access 40+ plus stock's (bid/ask volume and price) tick data at the same time; The chart has only 2 panes, SPY price pane and this indicator's pane. Thank you very much for your information.
both esignal and tradestation restrict the # of symbol data you can access on a single chart.... I believe with esignal the limit is 10-20. not sure about tradestation, it might be 10 or less. you can build strategies that run across hundreds of symbols in tradestation, but you use tradestation radar rather than a chart.
I am reading esignal EFS document. It's does not mention how to access multiple instruments' data in one indicator.
it's been a while, but it's there.... I can't remember if you do it via efs, or if you just apply several symbols to the same chart.
Esignal Scott, Thank you for the reply. Could you show me a snippet of code that could access multiple symbols in an esignal indicator ? I can't find an example in esignal EFS tutorial. Thanks,
Hi, I'm personally not a coder but between our Forums and the EFS KnowledgeBase, you should be able to find what you're looking for. For example, here's a thread on coding multiple symbols in an EFS routine: http://forum.esignalcentral.com/showthread.php?s=&postid=131158&highlight=sym#post131158 You can use the forum search function to find other EFS and symbol limit discussions. On this support page, you'll find links to the EFS KB. http://www.esignal.com/support/esignal/default.aspx Hope that helps. Thanks.
TradeStation allows up to 50 Data Streams on a single chart. But if you have multiple data streams on a single chart the orders can only be generate at end of bar. You can generate a end of bar stop or limit order that is executed during the next bar but can only place the orders at end of bar when using multiple data streams.
