I need to integrate Ea with instruction that closes all open positions in one chart when profit/loss limit are achieved and calculates break even level

I need to integrate Ea with instruction that closes all open positions in one chart, when profit/loss limit, defined in money,  is achieved. Break even should also be calculated and visible on the chart.

Today I have ea that regulates trail level, break even and profit and loss limits for any position opened manually in a chart. I would like to integrate for the case when more than one position is opened. In that case we should be able:

- to fix in money  total profit and loss limit in the input window (of all positions opened when more than one)

- to calculate the break even level and make it visible in the chart

So the integration should be activated only when more than one position is opened (manually) .

Ea should also fix the new break even level and trail level in total money: ex when total profit = 5 break even 0; when total profit = 10 trail level 10 pips
