Cent vs standard account

NOVOSKY supports two account types via config.json → "account_type". The trading logic is identical — only how the balance is displayed and sized differs.
Cent accountStandard account
config.json setting"account_type": "cent""account_type": "standard"
Example deposit500 USC ≈ $5 USD$500 USD
Telegram P/L display+55 USC ($0.55)+$0.55
Telegram balance681 USC ($6.81)$681.00
2% risk per trade2% of 6.81=6.81 = 0.142% of 681=681 = 13.62
Recommended pipeline: start on a cent account to validate the full system end-to-end (signals, execution, Telegram alerts, risk sizing), then graduate to a standard account with identical config.

​
How it works internally

The API returns balance/equity in the account’s native currency. For cent accounts that is USC; for standard accounts that is USD. The bot normalises balance to USD at the API boundary (_api_balance_to_usd()), so all risk sizing, P/L tracking, and growth calculations are always in USD. format_currency() then converts back to USC for display when account_type = "cent". Deal profits from the API (/history/deals → profit) are always returned in USD regardless of account type — no conversion needed.

​
Switching account type

Only change one line in config.json. No retraining, no model changes, no other config changes needed. 
"account_type": "cent"      // VT Markets Cent — balance in USC
"account_type": "standard"  // Standard account — balance in USD

​
Spread values per broker

Spread is passed to the backtester to correctly simulate execution costs. Using the wrong value inflates win rate by 5–8 percentage points.
BrokerAccount type--spread value
VT Markets BTCUSDCent or Standard16.95
IC Markets RAWStandard3.0
Spread from /rates is returned in raw points. For BTCUSD, 1695 points = $16.95 round-turn. trading.py handles this conversion automatically — you don’t need to adjust it. The --spread flag for backtesting takes the dollar value.

​
Broker diagnostics

Before going live on a new broker, check lot limits, margin requirements, and spread: 
python scripts/check_broker_limits.py
This prints:
  • Minimum and maximum lot size
  • Lot step
  • Required margin at current price
  • Current spread in points and dollars
  • Swap rates (long and short)
  • Stops level (minimum SL/TP distance)
