Apply sl equivalent to 350 dollars or euros

i have 4 different accounts with different currencies: USD, AUD, EUR. NZD I want to add a sl to all open trades; i might have 100 open trades on a single terminal.
These trades are all 1 of 2 tradesizes 0.35 and 0.14.
I want my sl on each trade, to be equivalent of $350 loss. This includes the smaller trades. I want each trade to have lose no more than $350 and no less than $330.
Note this is $350 in the accounts currency.

I do not want the input to pop up when i drop the script on the chart, however i will need to be shown where to change the value of $350 in the code in the event that i decide to change the maximum loss to $450 (for example).

Before ending this process and closing this job, i will expect to prove (by me) the script to be working on all 4 accounts with different currencies that i previously mentioned in first sentence.

I will also expect to receive the full mql5/mq5 source code before closing and ending the job.

If any of the conditions are not working as described above, then, the job will not be considered "to be completed".
