Python - fix bug in existing package by using percentage value from config (documented bug)

Fix 3 bugs in [login to view URL] a) with stop loss value. In case stop loss is higher than base price (base_price) of created order buy, error occurs. Exception: Failed: invalid_arguments Scenario to reproduce: set_sl_price 15000 set_contract_amount 10 set_num_orders 10 set_price_distance 10 set_base_price 10000 create_ladder start_update Note: current price is 10100 Solution to implement: set_sl_price has to be calculated automatically with percentage from config/parameter. e.g get price of lowest buy order, get percentage from config e.g 10% calculate price for SL price, update config (set_sl_price) simulation: last order buy: 10555.0 percentage 10% SL price should be: 10555.0 - 10% (1055.5) = 9499.5 [2019-07-03 00:21:19,590] [INFO] Credentials Verified DeriShell> set_sl_price 15000 [2019-07-03 00:21:43,920] [INFO] Updated Stop Loss Price to: 30.0 DeriShell> set_contract_amount 10 [2019-07-03 00:21:43,939] [INFO] Updated number of contracts to: 10 DeriShell> set_num_orders 10 [2019-07-03 00:21:43,944] [INFO] Updated number of orders to: 10 DeriShell> set_price_distance 10 [2019-07-03 00:21:43,948] [INFO] Updated price difference to: 10.0 DeriShell> fill_basePrice_askPrice Filling base price with: 10655.0 [2019-07-03 00:21:44,001] [INFO] Updated base price to: 10655.0 DeriShell> create_ladder [2019-07-03 00:21:44,003] [INFO] Setup initial ladder [2019-07-03 00:21:44,190] [INFO] Placing Buy Order for 10 contracts at 10645.0 ....
