eSignal (trading platform)
Significant cost, haven’t tested, very mainstream
Sierra Charts (charting, backtesting, options?)
Alternative to multi-charts. Posted message in forum on April 6, 2017 to see if auto trading was possible.

Better than multicharts according to write up from friend of Jim.

Elite Traders might be a good user forum https://www.google.com/search?sourceid=chrome-psyapi2&ion=1&espv=2&ie=UTF-8&q=elite%20traders&oq=elite%20traders&aqs=chrome..69i57j0l5.3711j0j8
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 Jim
Some problem with this that I don’t remember.

Sierracharts may do intrabar execution more seamlessly and have better rates, but TS may be easier to test on. Really a toss up.
SC does not have radar screen which may not be needed.
