If using any of the Session Open / High / Low / Close indicators in the building blocks, regardless if from the "Stop/Limit Price Levels" section or from the "Prices" section (it´s even worse if they are enabled in both sections), building is being slowed down by at least 50%. I´ve tested all day long and it definitely comes down to these indicators ONLY that are causing this. All other indicators/entry price levels do not cause any slowdown.
On 34 years of history data, using the H1 timeframe along with "1 minute data tick simulation", I am getting 31000 strategies / hour with everything EXCEPT the "Session Open / High / Low / Close indicators" enabled (which is what´s normal for my system since months) and am down to just 4300 strategies / hour with them enabled in both sections of the build blocks.
To test this, you also need to make sure to have the "Limit Time Range" option in "Trading Options" enabled and have a custom session set (e.g. from 1:00 to 23:59 just as an example).
Maybe there is a way to speed this indicator up? If not, you should at least add a warning that this one is extremely slow, as new users might not even notice how slow this makes the building process and think it´s normal that it´s taking that long.
Thank you.
