Mysterious errors with PL calculation and order execution
Issue:
There is a complex issue here in my beta PTMC 1.0.166 demo with AMP/CQG demo account for two days:
Seemingly randomly erroneous P/L calculation in tick/currency and seemingly false market prices or so. Sometimes order execution and P/L calculation is correct, but most of the times what is being displayed to me as actual market prices, open positions and P/L values are plain wrong, 3-10 ticks away from reality... :(
Example #1: PTMC shows -270 USD and 3 ticks loss on my short position of 3 LOT standard size Gold, while in reality 3 ticks loss of this shall be just -30 USD.

Example #3: It is a total mess here for me with CQG demo in beta.
Example #4: CQG data/price stream keeps flowing in PTMC for about 5 minutes even after I disconnect the PC from internet. So it is pre cached data locally on my PC...?

Hello PTMC Team,
Thanks for working or a fix, enhancement of the platform in order to eliminate this complex issue. After our Skype talks I wanted to leave here a summary of the issue for your reference and to be at hand and not to be forgotten because I want this tool, PTMC to became a perfect tool.
You know guys I have spent over 100 hours practicing with PTMC with various brokers in these weeks. Along PTMC I tried over a dozen other platforms as well during the past month.
Everything worked perfectly until my workspace included nothing else just a Scalper panel, a 1 day Renko tick chart and one single DOM, no indicators or any other charts.
But just when I felt I was closer to start live trading I did customize the workspace fitting to my style and concept, adding cluster chart, 10 days Renko tick chart, Order Flow Surface tick chart with volume indicator, 15min line chart and two separate DOMs along the Scalper panel. So from this moment when I was just ready to step forward, the whole positive experience has collapsed in a blink. It has turned out that the system is not rock solid and unsafe for live trading yet. If as a trader you cannot be absolutely sure that the prices you are being displayed are the true, actual market prices in any and every given second (up to 5 minutes delayed data) than you must not trade with the tool at all. :( Please do not get this wrong, I really want PTMC to succeed and its user base expand with rocket speed, but I am pretty sure that this "issue" is more than just a minor bug to be fixed, this about the fundamental basis of any trading platform: accurate, reliable and rock solid time and sales flow.
I really think that PTMC already does offer an better package overall than any other platform, a real edge over others (with a few things that could be enhanced), but all the other great features and the great design comes just after the fundamental, core element: accurate sales and time flow. This is the most serious element in trading online.
For now, until you develop the platform I completely stopped using it, testing it in my preparation for live trading. Despite that PTMC became my favorite platform. :)
I think there should be some sort of built in system that guarantees the accuracy of time and sales flow, which verifies the time and prices against a third reference clock and if there is ANY desync the platform itself shall STOP displaying the price flow in every chart, alerts should go off, the platform would prohibit opening new positions temporarily and allow only "FLAT ALL AND CANCEL ALL" at market price function to avoid causing money loss for the trader or even blowing up their own account while the desync occurs. But the optimal minimum would be if workspace load was not an issue, a factor in time and sales accuracy at all.
Also, data feed pre caching shall be disabled as it is. I have no clue how this is even allowed in a non simulation mode.
Thanks for your efforts and the opportunity for demo and testing and this community/forum.
Cheers,
Steve
