1. The market “does not know” which platform you are working with. The market “does not know” which time frame you are in. If the price of a financial instrument falls, then it falls on all time frames. I think that MTF systems have a right to exist.
2. XARD is a great system, but lives up to its name - too heavy. A profile can consist of two dozen financial instruments. If the XARD system is installed on all windows of the profile, the trading platform, together with the computer, "falls" under its weight. That is why I am always for "relief" in order not to load the platform with the computer. Sorry for the bad english.
