    for(Opportunity opp : Trigger.new) {
        if(opp.StageName == 'Negotiation' && 
           Date.today().daysBetween(opp.CreatedDate) > 90) {
            opp.StageName = 'Closed Lost';
            opp.CloseDate = Date.today();
        }
    }

global class CleanUpRecords implements Database.Batchable<sObject> {
    global Database.QueryLocator start(Database.BatchableContext BC) {

    }
    global void execute(Database.BatchableContext BC, List<Lead> scope) {
        delete scope;
