Hello, I've tried your suggestion and it does not work. The EA is still opening new positions.
If I'm not mistaken, putting a zero in any of the "entry protection" fields means that the EA disregards that feature.

Seems to be a bug, it supposed to stop opening new positions, I'll report it to to the dev.

I would substitute ManageClose with this:

void ManageClose(void)
  {
   // Do not Exit
   bool ind1long  = false;
   bool ind1short = false;

   if((posType == OP_BUY  && ind1long) ||
        (posType == OP_SELL && ind1short) )
      ClosePosition();
  }

This way it's like using Do Not Exit indi, closing would work only with set TP/SL.

> Disable entry or exit signal for single strategy EAs

It looks like ending new options will be useful:

Any ideas for better naming?

...

Besides that, I plan to add separate options for enabling the entires and exits of each strategy for the Portfolio Experts.

Thanks to you as well. Another working option!

Open New Positions: True
Close Open Positions: True

I think "Close Open Positions: True" is a bit ambiguous, because some may think that it means closing the positions immediately, like in the Bulk Operations features in MT5.

The initial wording proposed by Popov is perfect.

Allow opening of new positions: true
Allow closing of current positions: true

>  Popov is also going to implement this for each strategy in a portfolio EA.

That's right!

I'm thinking of having options like;

--- Individual Strategies  Control --
001 - enable entry - true
001 - enable exit   - true
002 - enable entry - true
002 - enable exit   - true
...
099 - enable entry - true
099 - enable exit   - true

...

I'm also thinking of showing the individual strategies' performance information in the chart. We will discuss this in a separate topic.
