Hi
@butcherboy
Here's an attached doc. The diagram explains it much better, but basically a Trailing BUY @ say $6.40 is placing a BUY order to trigger ASA price FALLS to 6.4 or below.
The 2nd part of this order is setting a "threshold", say about 5-6% of that trigger amount that the stock must then RISE before the BUY actually activate.
So example. $6.4 trail Buy threshold = say $0.32
So ORE plunges to 6.40 triggers and SP then rises to 6.55 = Nothing happens
Then SP plunges to 5.50 = nothing happens
However then it surges to 5.85. Your 0.32 threshold has been satisfied and your ORDER BUYS ON MARKET. = BUY complete at market price or 5.85 or there abouts .
End result you don't miss out on a buy and I instead of the 6.4 you are happy to pay, if it plunges for just a 1/2 hr ir so and returns back to a higher price, you end up with 5.85 in this example. Conversely, you could also end up with say 6.4 + 0.32 = 6.72 buy.
A bit of experience helps with setting the right price, but for massive swing days or bot induced volatility days, these can be a life saver or a bargain hunter.
Hope this helps.
