Hi D, as long as you don't mind I'm happy to pitch in.
Your example "...that if I were 'down' on a share yet the RSI were 85 I would find it hard to sell even though I know the likelihood is that it would fall back shortly......"
That scenario would mean I think, that you had bought initially at a higher price, then it fell quite a bit and you did not close out sooner, hoping it would rise, and maybe it did a bit, but it fell further so that it then ends up with an rsi at 85 but still below your buy in price?
Which is why you have a stop. The stop price that makes you sell should be "proof" that your decision was wrong. Ie you bought in the expectation it would rise, but it fell. Thats where support lines are important.
The whole concept between a support price and a resistance price is that the SP oscillates between these two prices:
Lets say Support 35p resistance 50p: If you buy at 45p and it falls to 41p, you have lost 10% which is a lot. But so what? it has been in this range before and gone back up. Your stop would be 34p because if it went below a level where previously it went to and recovered means that now the buyers are not there at 35p so the SP will likely fall further until new buyers are tempted in and a new support is found.
So you would be buying at 45p with a stop of 34p (11p) for a rise to 50p (5p) a risk reward of 1-2!!!! which is not worth the bet.
You would buy in when it bounced off 35p for the 2nd or 3rd time, say at 38p, risking 4p loss for a 12p gain to 50p which is a 3-1 risk reward which is the minimum you should be looking for. If you can't find it on a stock you "like" then simply look for another.
Remember, you are not forecasting what will happen just finding bets that put the odds in your favour with a profit sufficient to cover the occasional losses hence you need at least a 3-1 risk reward ratio.
Just buying a stock at a random price and if it moves a few % the wrong way, sell it, will I am pretty sure lead to losses over the (probably not so) long term
Buying loss making, small companies tends to make the moves and spread larger meaning losses can be greater.
If you want to play around look at big stocks like BP Shell, AAl ASZ Glen etc and see what the moves are made over the days/weeks/months to see if you can identify the supp & res lines. (do the trade on paper. you don't have to actually place hard earned on it and just practise by paper trading. (You may be surprised I think, how easy it is to do when it is an academic exercise taking all the emotion out of it compared to when you have real skin in the game and that in itself is instructive.
