Amborgio is right. Your screenshot is not enough.
This is the second thread you open for the exact same question. Please don't duplicate threads.
Of course you can! What do you exactly need?
No. Or blocks are to be used 'horizontally', not 'vertically', as in your image. The way it is used now is acting as an AND block.
I asked myself those exact same questions years ago, and my personal conclusion is that you need to accept a trade off. The more symbols you want to test/optimize, the less different strategies you can try. It's that's frustratingly simple. I you want to test first and then optimize a strategy, you definitely need good quality data. Otherwise, simply forget it. That requires a lot of time and patience, as well as money.
After years of trial and error (ie wasted money and time) I decided to focus on one kind of market only and ignore all the other unless someone else provides a good and tested idea. In my case I'm focused on forex only, not indexes, not stock, not crypto. Then I close my focus on intra day trading only and finally I concentrate on trend strategies only. I sounds simple, but trust me, there is a whole universe there to explore. Why those options and not others? Just for personal reasons. That is the kind of trading I feel more comfortable on. Because of that I selected a dozen of symbols to try, and that's it. All the other are excluded unless someone else tells me something really good about one of those I don't even look at. This combination of criteria makes my trading life more bearable. 
I hope this helps.
Sorry, I forgot to add that you should select the option "All(automated and..." in the 'Filter by group' tap of the block. That will catch all open trades right now no matter what happend to the platform.
That applied proce parameter is how the indicartor calculates its value candle after candle. What you want is what AlphaOmega is suggesting.
This is a question for real programmers. Anyone here? 
No offense but, is this a spam post? Are you trying us to get that EA, maybe?
I'm afraid that is an infrigement of fxdreema's terms and conditions. You should subscripbe for a month if you are interested in that project.
Seguro. Siempre que puedas, usa los indicadores de fxDreema. Sólo cuando no lo encuentres aquí, plantea la posibilidad de importarlo desde fuera de la plataforma.
I'm afraid. You will never get that in fxDreema. The EA will never know when a pip is the last pip for a candle. The closes you can get is knowing when a candles closed becaused a new one was created right now.
