I have a method. Pretty much a progressive inverted dip-buying. . 1. Divide trading funds into about 4 lots. 2. Buy around the peak of a strong up-day. 3. If it goes up significantly again... do it again. 4. Sell on a solid drop. 5. If it still goes up again, buy more. 6. Rinse. 7. Repeat. . I pay attention to resistance and support levels, and STOCHRSI level (0 oversold to 100 overbought). Investing.com is handy: https://au.investing.com/indices/aus-200-technical . So for instance today I placed a sell order @ $7.99, having calculated that would be about where the 20 day EMA would line up, as support. ASX200 actually went a little lower than that, but then came back up. . But if you're looking to simply buy, hold and ride it down... the ASX200 is technically holding an uptrend (just) with 6116, sitting above 20 EMA @ 6094. . So it's still anyone's game... .
