I also found out that you are prohibited from performing intrabar order generation AT ALL on 'dual' data charts, but you can for single instrument charts. I found you can apply a trade strategy to the first (data1) instrument, but not the second one. I tried putting together a dual instrument strategy to trade two correlated instruments. I go through a ton of charts all day long and this misbehavior eats me alive. I am keeping my previous charting package on subscription, because it functions very cleanly without a dozen extra jiggles per chart I want to view.

That it made it into production tells me that their current programmers don't actually use their own software to trade because these basic GUI programming misbehaviors are annoying as hell.

Jiggling the slider (that is already fully right) will get the screen filled again. Click enough and the chart gets squz up on the left side with most of the screen blank.

Also, if you use the 'squeeze' button to compress the bars, the chart is anchored to the left rather than right side. I had a trendline alert occur today and when I looked at the chart, I had to jiggle the scroll bar (which was already entirely to the right) to get the current bar to become visible again. I have noticed a few times that the most recent candle is not anchored to the right side of a chart and will just march off the right side of the screen. There have been painful times using EL/TS due to wonky charts and relatively arbitrary limitations costing me a bunch of wasted time. Account service for the way I use it is 9/10. Many times I get same day responses which is great this day and age. My TS account exec is decent and the tech support guys on the forum are well above average in knowledge and response time. I've been trading and programming in the real time enviro 25+ years. I'm almost 4 mo in on learning TS/EasyLanguage from scratch with the intent to mechanize my trading and take majority of my (huge) human error out of my trading. The few test trades I performed showed the brokerage/manual order entry fast and slick. Speed to getting a trading system up and get my capital working was my main driver. I went with TS because they have the raw data, autotrading software and brokerage wrapped up in one bundle. Glad that helped! Here is some direct insight to what I have seen recently with TS10.
