Multicharts .NET version (algo, options support limited)

https://www.multicharts.com/net/purchase/ Support is excellent. I thought this was hands down best charting platform found as of 4-5-2017 Sierra Charts is better according to write-up by friend of JC who said “when a symbol does not have enough history on the chart, the script gives an ‘ugly’ error message and doesn’t calculate anything” and said he experienced this in Multi-Charts. I think he was using the EL version though as he also complained of speed issues in general, and both complaints about multi-charts (bar history and speed), were general comments about other platforms as well. Since speed and other issues are greatly affected by the programming language, I suspect that Multicharts .NET version which compiles strategy rules using C#, would handle this just fine. I plan to test as of 9-7-2017

Interactive Brokers (platform and broker)

Allows lots of connectivity for outside platforms, no built-in algo tools, all third party, has options
