On the night of the May non-farm payroll data release, I traded the USD/IDR currency pair on WELTRADE, setting a take-profit point of 15,200. When the market hit 15,205, the platform delayed closing my position for 30 seconds, ultimately closing it at 15,080. My original profit of 1.2 million rupiah turned into a loss of 850,000 rupiah. This slippage only occurs during the early morning hours of Indonesian time (02:00-05:00 Jakarta time), when European and American markets are active but local regulatory complaint channels are closed. By July, my initial investment of 5 million rupiah had lost 2.3 million rupiah due to similar slippage. Yet, the platform continues to push "low spread trading" ads on LINE. I believe this is a scam.
