with the guided editor

Hi,
I am new to Drools rules. Can any one of you tell me how can
we write complex rules like below using Grided editor.
rule sequenceOfIncreasingWithdrawals
when
$account:Account($number : number)
$t1:TransactionCreatedEvent(fromAccountNumber == $number)
from entry-point TransactionStream
$t2:TransactionCreatedEvent(amount > $t1.amount,
fromAccountNumber == $number, this after[0, 3m] $t1)
from entry-point TransactionStream
not (TransactionCreatedEvent(fromAccountNumber == $number,
this after $t1, this before $t2 )
from entry-point TransactionStream)
$t3:TransactionCreatedEvent(amount > $t2.amount,
fromAccountNumber == $number, this after[0, 3m] $t2 )
from entry-point TransactionStream
not (TransactionCreatedEvent(fromAccountNumber == $number,
this after $t2, this before $t3 )
from entry-point TransactionStream)
$ai : AccountInfo(number == $number, eval($t1.amount.add(
$t2.amount).add($t3.amount).compareTo(BigDecimal.
valueOf(0.90).multiply(averageBalance)) > 0))
then
insert(new SuspiciousAccount($number,
SuspiciousAccountSeverity.MAJOR));
insert(new SuspiciousTransaction($t1.transactionUuid,
SuspiciousTransactionSeverity.MAJOR));
insert(new SuspiciousTransaction($t2.transactionUuid,
SuspiciousTransactionSeverity.MAJOR));
insert(new SuspiciousTransaction($t3.transactionUuid,
SuspiciousTransactionSeverity.MAJOR));
end
Thanks
