The DCA Ladder System
DCA (Dollar-Cost Averaging) is the strategy of buying more units of an asset as its price drops, lowering your average cost basis. SignalPipe implements a full DCA ladder system that automatically manages this process.
How the Ladder Works
Each deal starts at ladder level 1 (the base position). Every time a new buy signal fires for the same instrument while the deal is active, a new sub-position is opened, moving the ladder to the next level.
On Capital.com, each DCA step is a separate position (sub-position), all tracked together as one deal in SignalPipe.
| Ladder Level | Position Type | What Happens |
|---|---|---|
| 1 | Base Position | Initial buy that opens the deal |
| 2 | Safety Position #1 | First DCA buy -- averages down entry |
| 3 | Safety Position #2 | Second DCA buy -- averages down further |
| 4 | Safety Position #3 | Third DCA buy |
| ... | ... | Continues for each new buy signal |
Weighted Average Entry Price
The core of the DCA system is the weighted average entry price calculation. After each safety order, the average is recalculated:
new_avg_entry = (old_total_cost + new_position_cost) / new_total_sizeWhere:
old_total_cost= previous avg entry price previous total sizenew_position_cost= safety position fill price safety position sizenew_total_size= previous total size + safety position size
Take-Profit Recalculation
Every time the average entry price changes, the take-profit target is recalculated:
new_tp_level = new_avg_entry * (1 + tp_percent / 100)All open sub-positions in the deal are modified with the new TP level. This means every sub-position in the deal always shares the same take-profit price.
DCA Ladder Example
Assume a 5% take-profit setting and a base order of 10 units:
| Step | Action | Price | Size | Total Size | Avg Entry | TP Target |
|---|---|---|---|---|---|---|
| 1 | Base position | $100.00 | 10 | 10 | $100.00 | $105.00 |
| 2 | Safety #1 | $90.00 | 15 | 25 | $94.00 | $98.70 |
| 3 | Safety #2 | $85.00 | 22 | 47 | $89.26 | $93.72 |
- After the base position, the price needs to reach $105.00 for a 5% profit
- After safety position #1, the TP drops to $98.70 -- already below the original entry price
- After safety position #2, the TP drops further to $93.72
The more the price drops and the more safety positions are opened, the closer the TP target moves to the current price. This dramatically increases the probability of the take-profit being reached.
Safety Order Volume Scaling
The vyn premium strategy supports a Safety Order Volume Scale setting. This multiplier increases the size of each successive safety order. For example, with a scale of 1.5x:
- Base position: $1,000 worth of units
- Safety #1: $1,500 worth of units
- Safety #2: $2,250 worth of units
Larger safety positions at lower prices have a greater impact on bringing down the average entry, but they also increase total capital commitment. Choose a scale that matches your risk tolerance and account size.
