Repair EA for newstart of MT4-platform

Hi,

a) problem with the attached ea, which is used to start grid-rows (normally at the same time on several charts), is as follows:

I add the ea to the chart and let it run, whenever I restart my mt4-platform (maybe because of an windows-update for the pc) while the ea is working on this chart, the ea does not open any new trades- it stops to work.

you see this on the chart, the ea now says: lot size: 0.00

I have the feeling that this is an error of the ea (or even a bug)

the updated ea should start again after restart the mt4-platform and recognize the existing trades, which the ea has opened in the past.

b) second wish:

if you start the ea on a chart (f.e. on EURUSD) and set the magic-number to 0,

the ea should recognize all open trades (started manual or with another ea) on the mt4-platform concerning the specific curreny (f.e. EURUSD),

put it in its calculation and close all these trades (old and new ones), when the take-profit is reached.
