Addendum 1. Account manager and investor negotiation sample

1. AM. There are two trading systems A1 and A2. There are descriptions and statements of those systems.
2. I. Studied. I select À1.
3. AM. Select now: 1) deposit reserve size; 2) order reserve size.
4. I. More information, please.
5. AM.
   5.1. Size of reserve is measured in percents of deposit value.
   5.2. Let your initial deposit is $100000.
   5.3. Let you set deposit reserve size to 20%.
   5.4. It means that your capital is equal to $80000, deposit reserve is equal to $20000.
   5.5. Let trading position has opened.
   5.6. Let your deposit has grown to $110000.
   5.7. In this case your capital is equal to $88000, deposit reserve is equal to $22000.
   5.8. Let your deposit has lowered to $105000.
   5.9. In this case your capital is equal to $88000, deposit reserve is equal to $17000.
   5.10. Let your deposit has grown to $200000.
   5.11. In this case your capital is equal to $160000, deposit reserve is equal to $40000.
   5.12. Let then your deposit has only lowered.
   5.13. At deposit value $180000 your capital is equal to $160000, deposit reserve is equal to $20000.
   5.14. At deposit value $170000 your capital is equal to $160000, deposit reserve is equal to $10000.
   5.15. At deposit value $160000 your capital is equal to $160000, deposit reserve is exhausted, system stop.
   5.16. If trading is stopped by your command then deposit reserve will be restored.
   5.17. Deposit value at the trading stop is your capital.
   5.18. Let trading was stopped at the deposit value equal to $170000, then your capital is equal to $170000.
   5.19. Thus deposit reserve defends your capital value from possible losses.
   5.20. All our systems have automatic reserve control feature.
6. I. I see.
7. AM.
   7.1. Order reserve defends deposit reserve in above explained manner.
   7.2. Expected deposit reserve life time depends on order reserve size.
   7.3. Let order reserve size will be equal to 10% and deposit reserve size will be equal to 20%.
   7.4. Then system A1 can survive in approximately 2 losses consequence.
   7.5. A1 statements demonstrate that longer consequences arise approximately 4 times for one year of trading.
   7.6. Let order reserve size will be equal to 5% and deposit reserve size will be equal to 20%.
   7.7. Then system A1 can survive in approximately 4 losses consequence.
   7.8. A1 statements demonstrate that longer consequences arise approximately 1 times for one year of trading.
   7.9. On other hand, order reserve determines orders size, that is affecting to system profitability.
   7.10. Order size calculation is in lines 192-216 of system A1 code.
8. I. I see. Let deposit reserve size will be equal to 20% and order reserve size will be equal to 4%.
9. AM. For that order reserve size required deposit value is $50000 or more.
10. I. Server *******, login *******, password *******, deposit $100000, I have accepted account management agreement.
11. AM. Your master password will be changed, your read only password is À1234.
