As mentioned in a previous thread, I had a stop market order entered on ESST for $19.50 to cover a short position of 600 shares and was filled at $23.20. This was $3.70 of slippage to me. Has anybody experienced a worse fill than this in their trading career? I've never come close in 15 years, so wondering if anybody else has had a worse experience? To top it off, I spun and went long 600 shares @ $23.20 (automatically) and lost another $2.40 before I noticed what had happened. After all was said and done my account swung $4,500 in about 25 minutes while I was away from my computer, all on an $11,000 investment.
