Possibly the 2% of capital rule for the stop loss and work out the parcel size from that... so 2% of 40K is $800. Workout where the stop needs to be based on chart, make that equal $800. So take NDO for an example.
Stop loss is .189 (because I don't want to get stopped out on the exact support line of 19 when everyone else's stops get hit (would like advice on that theory too please!?).
I bought at 21 so that's .025 (sell order would be 18.5) $800/.025 = 32000 shares = 6720
? sound feasible ?
By the way, another dumb buy-in too here for me as the market came back to 20, so I would have easily got in at 20.5... got to frothed up about it leaving the station without - will take more of the advice above about letting the market come back to me.
