answer:Sorry about that error. It seems like the `positionSide` parameter was not sent to the API. You can try adding the `positionSide` parameter when creating the stop loss and take profit orders, similar to how it was done when creating the main order, as shown below: ```

answer:Chapter: "30 Things You Should Never Do in Athens" Athens is a spectacular city known for its ancient history, vibrant culture, and wonderful food. There is no shortage of amazing experiences to be had in this magnificent city, but there are also some behaviors to avoid if you want to enjoy your trip to the fullest and respect the local customs and culture. This chapter outlines 30 things you should never do when visiting Athens. One of the main mistakes tourists make is disrespecting historical sites. It is important to remember that visiting the Acropolis, Parthenon, or any other ancient site should be done with the utmost care and respect. Don't climb on the ruins, litter, or take any stones or other artifacts as souvenirs. Another thing to keep in mind when visiting Athens is to avoid disrespecting cultural norms. This includes dressing appropriately when visiting religious sites, such as churches or monasteries. Cover your shoulders and avoid wearing shorts or skirts that are too short. Additionally, never enter a church during the service if you only want to sightsee, as this can be seen as disrespectful to the parishioners. Wait until the service has finished and remain quiet inside the church, showing respect for both the holy space and the believers present. When visiting the city, some tourists may try to recreate the famous "Ancient Greek" look by wearing togas or other ancient attire. This is not only culturally insensitive, but it may also be seen as offensive and ridiculous by locals. Be cautious when crossing the street and never jaywalk, as Athenian drivers are known for their aggressive and speedy driving. Instead, use designated pedestrian crossings and traffic lights to ensure your safety. Avoid rude behaviors like loudly complaining about prices, especially in crowded markets or in earshot of vendors. Not only does this come off as disrespectful, but it may also ruin your experience in these exciting and bustling places. When using public transport, keep your voice down and avoid occupying more space than necessary. Also, never try to sneak onto buses, trains, or trams without a valid ticket, as fines and embarrassment may follow. Taxi drivers in Athens are notorious for overcharging tourists. To avoid this, always ask for a receipt when getting into a taxi and make sure the driver uses a meter. If you have any issues with a taxi driver, report them to the authorities. Athens is a city that prides itself on its culinary excellence, so when dining, never ask for ketchup, HP sauce, or other foreign condiments, as this is seen as insulting to the chef. Instead, embrace the flavors of Greek cuisine and ask locals for recommendations. Do not litter, whether you are on the streets or visiting natural sites. Treat the city and its environment with respect by using trash cans and recycling bins provided. Avoid walking around with your camera around your neck or with your phone in your hand at all times. Not only does this label you as a tourist, but it also makes you an easy target for pickpockets. Keep your belongings secure at all times. When purchasing souvenirs, avoid buying cheap knockoffs or replicas of famous artworks. Instead, support local artisans by purchasing authentic, high-quality goods made in Greece. Do not expect everyone in Athens to speak English. While many locals do speak English, attempt to learn a few basic Greek phrases to show your respect for the culture. Avoid comparing Athens to other cities or making derogatory remarks about the city's cleanliness or appearance. This can be seen as disrespectful to the pride locals have for their history and culture. In summary, to enjoy your time in Athens to the fullest, make sure to follow these guidelines and show respect for the city and its inhabitants. By understanding the do's and don'ts of visiting Athens, you can ensure a memorable experience that leaves you feeling enriched by the city's history, culture, and hospitality.
