A cryptocurrency trading system, delivered directly, but the key is — can you really use it well?
Big Cycle Trend - Clearly determine whether it is a bullish or bearish market, and decide whether to go long or short accordingly.
Enter the market on a small cycle (Note: the span between small and large cycle levels should not be too great, ideally 4-6 times) - use small cycles to filter reverse fluctuations and adhere to the right-side trading principle.
Set stop-loss - based on the trading system of the small time frame chart.
Move the stop loss to the cost price - only move it after a "reasonable" profit appears in the small cycle.
Entry operation completed - close the small time frame charts, no longer pay attention, and return to the larger time frame charts for analysis.
If the stop-loss is triggered, repeat the above steps 1 to 5.
If the long-term trend is favorable, continuously move the stop loss in a beneficial direction—adjust according to the trading system of the long-term chart.
If the stop loss (or take profit) is triggered, then repeat the above operation process.
