Not read this but am sure it will, add a shared link rather than pictures, this way block internals can be seen: projects - get a shared link - generate - copy address bar - past here. if you change symbol to any symbol in all relevant blocks in EA then only 1 trade will be placed on account:
You have ratio at 100, so bot is likely defaulting to a lower size... try something like1.
To close/delete use pink blocks
Crypto can take a wile, you can go to https://fxdreema.com/support and ask... may sort it quicker.
In the "group" settings you can select specific symbol to only work with the current chart symbol. I same symbol on other chart set a group number for the specific trade.
Read the answer a couple of posts up
Try this, be careful GMT is actually reading GMT time, I have set (period of time) +2 as this block doesn't use GMT, set to your server offset, the only way to stop trading is to put a block in that prevents it.
Set up some logic saying what just fired, you can print on screen/journal... many places, just something that will show you what just happened.
Not 100% sure what you mean? You have nothing to draw anything, not even comments.
There is a lot in that to dissect, put your variables into a comment to check if you are getting the values you expect. You should use text (code input) for code., come back if you need more help when you you've tried rhis:
Create with pink blocks: https://fxdreema.com/shared/9GjYvLjS
No "place relevant trade" was just my way of saying the trade you want to be placed in that situation...
This is martingale, sounds good but is unlikely to be. In a separate tree for each trade - pips away from open price (-will work when trades in a negative) - place relevant trade (either set bigger lot, or loop lot adjusted to what you want, like *2).
Try this.

Hope this works 
try adding this to the function, not tested though:
void CloseAllPositions(ulong MagicStart)
{
for (int cnt = PositionsTotal() - 1; cnt >= 0 && !IsStopped(); cnt--)
{
if (PositionSelectByIndex(cnt))
{
ulong ticket = PositionGetInteger(POSITION_TICKET);
long magic = PositionGetInteger(POSITION_MAGIC);
// Only close positions matching the EA's magic number
if (magic == (long)MagicStart)
{
sTrade.PositionClose(ticket, 100);
uint code = sTrade.ResultRetcode();
Print("Close result code: ", IntegerToString(code), " | Ticket: ", ticket);
}
}
}
}
Yes and more, the best way to work things out even when you have what to do, is put the values in a comment, or draw objects to show what is visibly happening in backtest, you can then use this to check what you want/think is happening... You can try this, connect off yellow what to do when distance is true: 
This is only buys and is done on the on trade tab to separate the first trade from multiply lot trade.
Like the picture, in the condition choose a to reset (to stop multiple notifications):
