Translated with Google. For this strategy we use three currency pairs: EURJPY, EURUSD, USDJPY. To determine the opening and closing of positions using two values: REF = Average volatility mean of each pair of currencies, calculated using the last 1000 daily bars; SCP = Percentage deviation from the initial reference price calculated every second for each currency pair. SELL OPEN and CLOSE OTHER POSITIONS: When SCP of a currency pair is greater than REF, all open positions are closed and a SELL position is opened with the currency pair which is greater than REF. The amount used is generally dependent on the relationship between SCP average of the three currency pairs and SCP of the currency pair used (average SCP pairs EURJPY, EURUSD, USDJPY / SCP pair used * equity). All the reference values ​​of the initial price are updated.  No stop loss. No take profit. BUY OPEN and CLOSE OTHER POSITIONS: When SCP of a currency pair is less than -RIF, all open positions are closed and will open a BUY with the currency pair that is less than REF. The amount used is generally dependent on the relationship between SCP average of the three currency pairs and SCP of the currency pair used (average SCP pairs EURJPY, EURUSD, USDJPY / SCP pair used * equity). All the reference values ​​of the initial price are updated. No stop loss. No take profit.
