I am considering the possibility of moving my option positions from Lightspeed to TOS. I trade mostly options on SPX. Lightspeed uses IB as their clearing firm. I have the option of using LiveVolX or the TWS trading platforms. I am suppose to get .50 cent per contract at Lightspeed but shockingly the exchange fees & Regulatory fees for me seem more then the broker fees themselves!! These fees seem to vary greatly. I think it depends on if you are adding or taking liquidity and if you are trading weekly SPX or monthly SPX options. Here are some real examples: 28 contracts - Total Fees - 28.93, 4 Contracts - Total Fees - 6.53, 4 Contracts - Total Fees - 4.12, 16 Contracts - Total Fees - 18.13 As you can see .50 per contract is actually a smaller portion of the total. I was able to negotiate with TDAmeritrade $1.00 per option contract without a base commission and WITHOUT exchange fees. I should save a little with SPX options. I like the TOS platform and the Android App has evolved to do complex options. The stickler is they want $175,000 in position and cash value in the new trading account before the agreed upon commission rate will kick in. Otherwise I trade at a higher commission rate. I have Reg-T Positions and cash serving as margin at Lightspeed\IB. To do a complete transfer take at least 10 days. This means that you cannot trade or adjust those positions for at least 10 days or more. Normally this would be a rather dangerous position to take for an option trader. However I am thinking of a possible innovative solution. I could fund the TOS account with enough funds to do adjustments with TOS for two weeks. When the IB option positions flows into TOS options positions that oppose each other they should cancel and options that are the same should add to each other. For example if the IB position is short 31 Aug 2400/2350 and I do an "adjustment" trade in TOS with long 31 Aug 2375/2350 my conjecture is that the 2500 Put will disappear because you can't have two opposing positions in the same account. The resulting positions at TOS should be Short 2400/2375 Put after the position transfer into TOS. I would be transferring a Reg-T account to a Reg-T account. The adjustments can be broken down to credit or debit verticals at TOS. On the IB account I sometimes I buy a naked Long Put for protection. In those instances I think I would need to close the Long Put at IB because I would be way over margin if I shorted a naked put at TOS. I could transfer the remaining cash later. I need to confirm with TOS if they take whole options at once. THEY SHOULD. They have more Savvy programmers at TOS. Incidentally IB internal transfer of positions is instantaneous. However for options the option internal transfer process is RATHER STONE AGE(Really). Even though you specify a set of positions for internal transfer the system actually transfer one option position at one time!!! So if you select a vertical to transfer and the system transfers the short first the receiving account will be over margin and the transfer stops. If the system transfered the long position first the sending account will be over margin because it will be net short and the transfer stops. Remember this is an internal IB positions transfer between account you own!!! I told them about this problem but I doubt if they will do anything. I once told them about a major bug in their Android app. It took them years to correct it. Regardless, does anyone see any problems with what I am "considering" to do? I believe I have enough cash funds to do adjustment at TOS for two weeks and even open a new trade.
