I am an older person with EE experience in ORD 6 equipment (Nike I and AJAX) and the IBM conversion from vacuum tubes (600 and 700 series) to transitors. LOL
We had a mean time to failure orientation.
PC redundancy is my cure for having data and communication capability at all times. I actually have other PC's tied to phone lines. I post pics of my set up a while back on ET. You can see six screens in the pics where one is a TV. The arc they are in (68cm) has the four screens in the middle.
I am just an amateur and I limit my self to holds of up to 100K shares in any given equity stream (multiple accounts). I try to net 10% per 6 to 8 day cycle. I panic if I do not have data available one way or another. I trade by phone on equities so I can use broker for backup. Equities are a consideration vis a vis losing feed. To exit a 100K share position I have to trade into the peak, across it , and maybe go down the other side in a portion of a day. The two constraints are to not affect the market regarding block size nor to trade more than 10% of the cummulative trading for the day. For a 30 dollar stock it takes 30 trades to exit in a market that does 1 milliion or so shares a day. The slippage, for me, has approached 200k on a 17 point net by not pacing the cummulative volume. Losing data feed is an issue under these circumstances.
Regarding futures, I am now electronic (gave up phone on DJXX when eminis were invented.) With this set up I have had losses during brief periods of disconnect (for minutes to a portion of an hour) that are in the four digit range at a frequency of that is quarterly at best. This is a drag for me. I feel uncomfortable when my data (from multi sources) gets out of synch because of overloading at sources or on down the feed line.
I have three phone lines (see pics) to get out of trouble if need be.
I guess being born in the depression, dealing with military reliability needs, and dealing with large mainframes has biased me to one extreme. The financial aspect is a consideration too; I am very risk adverse and some people feel that I am greedy and I focus too much on being very efficient in taking capital out of the market.
