Changing existing order script

I want to add the following item in the script

Changing lotsize  per range

( the exesiting script should be adapted for buy/sell/modify section without/instead create a fully new program)

These option should be added  so i can define in the TAB

1. From which entry it should increase/decrease lotsize ( first, second, third, fourth) - see example

entry point order 2. maximum lotsize in total of all open orders : max risk 1.5

3. accountsize

Every account size has it standard set of max lotsize for 

100 K 0.3 max lot

200 K 0.6 max lot

300 K 0.9 max lot

400 K 1.2 max lot

500 K 1.5 max lot

600 K 1.8 max lot

700 K 2.1 max lot

800 K 2.4 max lot

900 K 2.7 max lot

1000 K 3 max lot

The goal is to have this as output

testing range

input rage 2455 to 2548

step 25

max lotsize 0.4 ( script should work with any range or lotzie) 

max risk 1.5 %

What should the script create (for sell or Buy limit/modify orders)

With Buy Order (example given on 100 K account)

Low risk 2458-2457

entry point order 2458 lotsize 0.325

entry point order 2457.75 lotsize 0.3

entry point order 2457.50 Lotsize 0.20

entry point order 2457.25 Lotsize 0.20

Medium risk 2457-2456

entry point order 2457 lotsize 0.015

entry point order 2456.75 lotsize 0.15

entry point order 2456.50 Lotsize 0.10

entry point order 2456.25 Lotsize 0.10

High risk 2456-2455

entry point order 2456 lotsize 0.05

entry point order 2456.75 lotzie 0.05

entry point order 2456.50 Lotsize 0.025

entry point order 2456.25 Lotsize 0.025
