Algorithmic trading focused on survival, not speed.
AURORA PRIME is not designed for fast profit.
It is designed for survival, stability, and long-term capital preservation.
This system was built under the philosophy that:
“Staying alive in the market is already a win.” - 版本: 1.0
MelloRiskCalculator tells you the lot size for the risk you choose, before you place a trade. Drag three lines on the chart, entry, stop loss and take profit, and the panel updates at once. It is a calculator only: it never places, changes or closes orders.
How it works
- Risk as a percent of balance, a percent of equity, or a fixed amount of money
- The lot is rounded down to the broker's lot step, so the risk is never more than you asked
- If even the minimum lot risks more than you chose, the panel says so
- Commission per lot can be included
What you see
- Lot size, risk and reward in money and in percent
- Reward to risk (R multiple)
- Stop and target distance in points, and in pips on 5 and 3 digit symbols
- Margin for the lot and its share of free margin
- Money per point at that lot
- Buy, sell, buy limit, buy stop, sell limit or sell stop, from where the lines are
- Shaded risk and reward zones with labels next to the lines
Lines
The entry can follow the market price (ask for a buy, bid for a sell), or stay where you drag it. Flip turns a buy into a sell with the same distances. Reset puts the lines back around the price. Lines and panel settings stay when you change the timeframe.
Accuracy
Money values use the broker's own tick value. Pairs whose base currency is your account currency, such as USDJPY on a USD account, are converted at the exit price, as the terminal does. In our tests on EURUSD, XAUUSD, USDJPY and GBPJPY the lot, risk and reward matched the terminal's own profit calculation, and the margin was within 0.05 percent.
For EA developers
Buffers on the open bar: 0 lot, 1 risk money, 2 reward to risk, 3 margin. Closed bars are empty.
Strategy Tester
Lines are drawn in visual mode. Without a visual chart there are no lines, so the buffers are empty.
Important
This is a calculator. It gives no trading signals and does not promise any result. Trading leveraged products involves a high risk of loss.
