hello i have a programme write on python the programme have to download all the sell order and all the buy order make a comparaison of their price and send a result when it find a great benefit.

But it have a probleme because the sell order are compare of the referral price this one is not complete and the goal is to compare the buy and the sell order.

So i search someone for help me to finish the programm because i am not able to replace the referralitem by the buy order i know how to download it but the problem is about the refferral i give you the source code

Module is missing. I would assume its one of your imports at the top

```auto
import urllib.request
import ast
import decimal
import requests
import json
import time

```

I suggest you check if all of those are installed on your system:

yes but it is not the problem the problem is  
refUrl = get\_url\_content(“[https://esi.tech.ccp.is/latest/markets/prices/?datasource=tranquility”](https://esi.tech.ccp.is/latest/markets/prices/?datasource=tranquility%E2%80%9D));  
the referal have to be the buy order price so the data but it have already a data var so what can i do and what does i change?

`/markets/prices/` are not the buy/sell prices. They are average / adjusted prices used for taxes, insurance etc in the game. You can generate your ID list from this one, but this one [https://esi.tech.ccp.is/ui/#/Market/get\_markets\_region\_id\_types](https://esi.tech.ccp.is/ui/#/Market/get_markets_region_id_types) is the one you should use to generate that list

If you want the order prices, you need to use the right enpoint for prices [https://esi.tech.ccp.is/ui/#!/Market/get\_markets\_region\_id\_orders](https://esi.tech.ccp.is/ui/#!/Market/get_markets_region_id_orders)  
This is where you’ll have sell / buy prices, but keep in mind this is all the order in the game, so you have to parse it, get the min/max or whatever you want, using all pages before you can display what you want.

In the future, you’d rather put code within code tags (write `` your code ``, also it’s “preformated text”)

i know that is why i need to change it and adapt this code to my fonction

data =   
page\_id = 0

```
while True :
	res = requests.get(url, params={'page': page_id}).json()
	if not res : break
	data.extend(res)
	page_id += 1

return data

```

return data1  

```

for identifier, value in load\_all\_market\_buy(10000001,10000004).items():  
print (len(value))  
identifier += 1  
for identifier, values in load\_all\_market\_sell(10000001,10000004).items():  
print (len(values))  
identifier += 1`  
this code download all the buy and sell order of the market on the region 10000001 to 10000004
