Quick question on which I'd appreciate a little help if anyone has any opinions. I'm looking for a software application that will read market data, display price charts and provide some sort of scripting language to allow me to overlay shapes (mainly lines joining locations in price and time). Ideally it'll use a published market data standard, so that I can convert my market data into its format and push it in. Don't need anything else (e.g. broker connectivity). All my other requirements (backtesting, execution etc) are met by my suite of custom applications. At the moment I am using NinjaTrader and NinjaScript, and it has become unworkable for many reasons. I'm just looking for something to allow me to eyeball the output of ideas and backtests on a chart. You can do all the number crunching in the world, but sometimes you just need to see stuff overlaid on a chart. Be grateful for any ideas. Thanks.
