After such index adding:

sql_coursor.execute("CREATE INDEX timestamp_index ON stats_swaps (started_at);")

performance such select

    t = (timestamp,pair[0],pair[1],)
    sql_coursor.execute("SELECT * FROM stats_swaps WHERE started_at > ? AND maker_coin=? AND taker_coin=? AND is_success=1;", t)

works 5 times faster, so it might be good to index by timestamp by default

@tonymorony Done, please try to remove the index you added manually and then update MM2.
