You saw the quote for $ARB at 0.1545 USDT, up 16.165% in 24 hours. It’s not far from the 24-hour high of 0.1593—so your hands start itching.
Hypothetical scenario: You originally planned to invest 100 USDT to buy $ARB at a fill price of 0.1400. After the price rises, you temporarily decide to add another 200 USDT—just because, “It’s already gone up so much, it should still keep moving.” Your total planned investment increases from 100 to 300, but the rationale doesn’t.
If the price falls back to 0.1400, the original 100 USDT would nearly break even. The additional 200 USDT would only be worth about 181.23 USDT, for a total of about 281.23 USDT, not counting fees—so you’d be down about 18.77 USDT. Changing the plan temporarily makes the new position carry drawdowns you hadn’t planned to tolerate in advance. The problem is that you changed the amount without new conditions.
Which step changes? Before placing the order, set the total investment in stone. If you add money temporarily, you must first write down the trigger conditions and the invalidation line—“the price has already gone up” doesn’t count. If the conditions were already written and truly triggered, then this case doesn’t apply. During self-checking, write the original planned amount, the changed amount, and the reason for the change on one line—if the reason can’t be verified, don’t change it.
