Shorting fallbacks from morning stock spikes

This is an easy-going little low-stress spreadbetting sideline alongside my more serious trading. Occasionally it fails, but for me it works more than 4 times out of five, and is profitable enough for me to keep doing it. I do it in a VERY unsophisticated way, for small money, using no indicators. I imagine that active traders employing greater precision can refine it for greater success at much bigger stakes - but here's how it works for me, with a couple of recent examples from a few days ago.

At 8.15am (when it becomes available for free - I am not a paying subscriber there) I call up the 'Percentage Gainers' list from Advfn's 'Toplists'.
The biggest gainers tend to be among penny shares which I ignore. Among those that have risen 7% or more I pick out the 3-digit/4-digit priced stocks There's usually between 2 and 5 of them). I quickly check out the reason for the rise (usually news related) and the bid/offer spread, then glance at a minute-by-minute rolling price chart (usually at Spreadex, sometimes at IG) to see if it looks like the initial spike is beginning to fade. If in my casual judgement it is, I slap in a downbet - sometimes at the minimum stake allowed, but usually at a stake involving a margin requirement of around £200+ which I then repeat with multiple bets the same size if it looks like it is starting to move convincingly my way. (I prefer to do it in this fragmented fashion because it allows me to individually cash in the initial tranches when they've moved far enough into profit).

More often than not, the downward drift happens quickly enough to cash in my gains the same day - sometimes within the hour. Sometimes it doesn't, and in the minutes before the market closes I will decide whether to let the bet run on to the next day (which I'd rather not do), or close it (maybe without it yet having moved into a worthwhile (or any) profit) rather than risk it opening up next morning.

EXAMPLE: When Melrose Industries (MRO) spiked at 8am on Aug 1, I placed four £2pp downbets, at 0818 (543.6p), 0850 (540.4), 0851 (540.4), 0851 (540.4).
At 0934 I closed all four, at prices between 534.4p and 535p, banking £52.40

EXAMPLE: When Rentokil (RTO) spiked at 8am on 31 July, I placed a £3pp downbet at 0835 at 383.5p. At 1436 I placed a further £3 downbet at 383.4p.
I kept those bets open overnight, cashing them in at 0809 on Aug 1 at 368.05p, banking £92.40

I don't always get it right. I might occasionally bank a loss of £100-£150. And because I am often content to bank wins of £50, £90, or sometimes tinier, so for winnings to outweigh losses I do have to win a lot more often than I lose. This morning I placed downbets on Close Brothers (CBG) and Secure Trust Bank (STB), all of which are into profit - which I could bank or could keep open.

For spreadbets I mostly use Spreadex, sometimes IG. I use IG for my sharedealings.

I would be interested to hear feedback from anyone trying the same game of downbetting selected morning spikes.
 
I generally avoid doing this on a Friday - because if I do need to let the bet run overnight, there's too much risk of things happening worldwide over a weekend. That Melrose bet was an exception but it looked like moving quite quickly my way. I was able to close it and bank a profit by 9:35am.
 
Some might ask "Why the hell did you cash in so soon - you could have made 3 times as much that day?" And they are right. I could just cash in part of my stake perhaps and place a trailing stoploss on the remainder. But I am 77 and this is a casual low-stress hobby. I am happy to bank say £50 and switch off for the day. As a very rough guide, I tend to get out once the spike has halved.
 
Took my eye off the ball at Close Brothers! Out of it now but managed to squander the gain that was showing earlier. Should been watching instead of over here scribbling :-/

Luckily made up for it elsewhere.
 
At 0843 this morning the Yougov spike is still rising but I am watching for it to look like peaking soon and will pounce with a downbet if it does.
 
Placed a downbet on Yougov at 0910. I'm not going to continue with live reporting here - just giving a brief insight into how it works. This one may yet go wrong of course.
 
That worked nicely. I opened 6 downbets on Yougov totalling £26pp. Closed 4 of them to bank £157 profit, and allowing two of them (£1pp and £5pp) to run on till tomorrow, with trailing stoplosses in place.
 
Yougov did drift down a tiny bit this morning, but not enough to keep me interested so I closed the remaining bets for a gain of £8.10, bring the total to £165.10 and went off to do some gardening.
