 =Conclusion=
-Waste difference between results of agents when running in two different conditions showed problem of agent based simulations when applied to real life data. Problem lies in fact, that while model might seem to be logical, working and generating interesting results, in fact these results are not appliable to real life.

-Another problem of model and market models in general, lied in fact that model would be either to simplified, or too complex. To balance need for simple model and model which would implement many different real life situations and difference of users, developers of basic model used many variables, which could be hardly translated to „real life“. It could be said, that it is problem only of this model, but this problem is very often with simulations which should bring some real-life implementations.

For example lack of proper function for input of data from any other type of file than .txt in special format of data, which required change in file for data transfer from source (Patria).

 =Method=
 Biggest quality of developer is doing task efficiently and reusing already done solutions  of problem. During developement of model and simulation I have reused model of Multiagent simulation  of market as a basic representation of market. For second simulation, where actions of agents do not have any result on market price, i have used exported data of observed market product (SLVR.L) for price making. I have used opening and closing prices for 150 consecutive days, therefore simulation has fix length of 300 steps.
-Fact, that our agents were not able to change price in second simulation, provided many benefits.
